    How to Dry Tomatoes And Store In Olive Oil

    Jump to Recipe

    A tutorial for the time-honored tradition of safely drying tomatoes and storing in olive oil at room temperature without canning. It's a great way to preserve tomatoes to use in any recipe calling for dried tomatoes.

    How to dry and store tomatoes in olive oil - tomatoes in jar

    Some links in this article are affiliate links and if you click on them I will receive a small commission at no cost to you.

    IMPORTANT NOTE: This is NOT a tutorial for canning tomatoes in oil, since there is NO way to do that at home safely. I am not recommending that. Removing all the air from the covered tomatoes would create an environment for botulism to grow (low acid + no oxygen). This simply shows how you can cover completely dried tomatoes with oil (and NO other ingredients), screw a lid on and store at room temperature.

    This tutorial for drying tomatoes and storing on the shelf in oil is how I've preserved and kept my dried tomatoes for years.

    You'll find them in a vintage canning jar covered in olive oil and sitting in a cabinet in my kitchen.

    The tomatoes are SO much easier to use this way, versus simply dried and packaged: you can cut them up immediately to use in Italian pastas, over salads, and in dips - all without needing to rehydrate first in water.

    Background

    I learned of this technique for drying tomatoes from well-known local food preservationist writer, Jan Roberts-Dominguez in the Oregonian newspaper in the 1990s. (I actually taught myself to can using some of her articles and many of her recipes are my favorites even now.)

    She always used recommended USDA guidelines and her preservation recipes were tested and approved.

    Once I started using her method for drying tomatoes and storing them in oil, I never looked back. It's a huge money-saver as well as a great item to have on hand for recipes.

    Here's my note about the safety of this method:

    Many of you know I'm big on food safety, and I don't do things based on the "I've done it for years and it's never killed anyone" train of thought.

    However, this particular preserving method is a time-honored technique that has stood the test of time for two reasons:

    1. Tomatoes are naturally acidic (and I never add any fresh garlic or herbs)
    2. The tomatoes are dried until they are still pliable, but no liquid comes from them when I test them with my fingers.

    As an added precaution, I also use Ms. Dominguez's recommendation to dip them in red wine vinegar to help extend their shelf life - which increases the acidity as well.

    However, in 2010 I came across a newsletter that said the National Center For Home Food Preservation was no longer recommending storing dried tomatoes in olive oil.

    Why?

    "Preserving tomatoes in oil is currently not recommended. Oil may protect botulism organisms trapped in a water droplet. Furthermore, oil may have a deleterious effect on lid gaskets and at least one manufacturer of home canning lids recommends against it."

    You can imagine I was NOT happy with this. Especially since:

    1. The tomatoes are dried and don't contain "water droplets."
    2. The oil doesn't touch the lids.

    But mostly I wasn't happy with this because when I tried to research this new recommendation, I wasn't able to find any other site or research to back up this claim.

    Seriously.

    So I emailed Ms. Dominguez and asked if she had heard this and what her thoughts were.

    She had not and basically echoed my thoughts - that if the tomatoes are truly dry and not packed with any fresh herbs or garlic there should be no problem. The vinegar dip she recommends also helps tip the acidity level.

    9/3/11 Update:

    I found this information that mirrored my own from the book, How to Store Your Home-Grown Produce: Canning, Pickling, Jamming, and So Much More by John and Val Harrison:

    For years we stored in oil by simply placing the produce in a sterilized jar and filling the jar with oil, agitating to get any air bubbles out before sealing...when we published this on our website we were deluged with emails warning that we could get botulism from this…

    When we researched this...we discovered that it was first mentioned on a Canadian website in reference to an outbreak of botulism from a restaurant...this was picked up and repeated...until it became a fact as far as casual searchers were concerned.

    (We) decided to consult a food scientist directly. He explained that there was a theoretical risk that small droplets of water adhering to the vegetable would provide a growing medium for botulism. He couldn't quantify the risk, not being a statistician, but comparisons with being struck by a meteor...were mentioned. He wouldn't go on record as saying it was safe, although he said he would have no concerns personally about using the method.

    9/5/17 Update:

    The Oregon State Extension Service lists this as a safe way to store tomatoes!

    Because of their acidity, unseasoned (i.e., no vegetables or herbs) fully dried tomatoes may be safely stored in oil at room temperature. (Refrigeration may delay rancidity, however). The tomatoes will soften more if quickly dipped in bottled lemon or lime juice before being placed in the oil. The tomatoes can be flavored with dried herbs and garlic. NOTE: Dried tomatoes-in-oil mixtures with [fresh] garlic and/or herbs MUST be refrigerated and used within 4 days or frozen for long-term storage.

    I'm glad to be able to give you up-to-date information about storing dried tomatoes this way.

    And let me tell you- these are sooo easy and tasty and a fraction of the cost of store-bought, I'm pretty sure you are going to love these as much as I do.

    How to Dry and Store Tomatoes In Olive Oil Video

    We made this video after a number of readers asked how to tell when the tomatoes are dry enough, as well as other details.

    Tutorial for Drying Tomatoes & Storing in Olive Oil

    Drying Tomatoes-prepping tomatoes_600


    1. Wash tomatoes, cut the top core off and cut them in half.

    Remove as much of the seeds as you can by running your thumb down the insides. It sounds tedious, but goes rather quickly. TIP: I use an over-the-sink cutting board with a cut-out that makes it easy to cut and scrape the pulp right into a bowl set below the board.

    Note: I prefer to use only plum tomatoes for dried tomatoes to store in oil. They make better dried tomatoes since they're more meaty.

    Drying Tomatoes on dehydrator tray

    2. Line the tomato halves on a dehydrator tray, cut side up.

    This is important, otherwise you'll get a lot more juice run-off as they dry and the cut side sticks to the tray, making them harder to turn. As you can see, I really pack them in there because they shrink as they dry.

    3. Dry at the manufacturer's recommended 135 degrees. 

    (I love and use a 5-tray Excalibur Food Dehydrator.) Leave them for about four hours and then do the first switch: turn them over and turn the trays around. None are usually dry yet, except maybe a few really small ones. Let dry for another 1-2 hours before checking again. At this point, there will be some dry tomatoes and you'll need to remove these (I set them in a large bowl or baggie) and continue drying the rest.

    Alternative oven-drying method:

    Cook tomato halves in a 170-degree oven for about 3 hours with the oven door left open about 3 inches for moisture to escape. Then turn the tomatoes over, cut side down, and press flat with a spatula. Continue baking, turning the tomatoes every few hours, gently pressing down, until the tomatoes are dried, up to 9 hours more. Check often since some tomatoes will be done quicker depending on the size and moisture content. Aim for a leathery feel that will bend but is not crisp, and no moisture appears when pressed all over with your fingers.

    What does a fully dried tomato look and feel like?

    (for a better visual of this, the video above shows more on this process)

    Drying Tomatoes-pliable dried tomato

    Your fully dried tomato halves should be dry and leathery with no moisture coming out from them when you push them with your fingers.

    You should be able to bend them like shown in the picture above.

    If some get a bit crisp in places, it's OK, but don't let them all get that way- there's no amount of oil that will soften them up again.

    (TIP: if some get too crisp, you can whir them up in a food processor or blender to make tomato powder which makes great tomato paste with a bit of water added!)

    As you continue drying tomatoes, you can start putting the fully dried halves in a jar, starting with a vinegar rinse:

    Drying Tomatoes-vinegar dip

    4. Dip dried tomatoes in vinegar.

    Fill a small bowl with red wine vinegar and grab some tongs. Dip the dried tomato halves into the vinegar and then let the vinegar drip for a minute before placing in a quart jar.

    Drying Tomatoes-dipping in vinegar

    5. Continue dipping the dried tomatoes in vinegar.

    Let them drip and place in the jar until the jar is full to the shoulders of the jar. It's okay to press down on the tomatoes to remove air and fit more into the jar.

    Drying Tomatoes and stored covered in olive oil

    6. Add olive oil to the jar until the tomatoes are covered. 

    You will need quite a bit of oil, but you will be able to use the oil for salad dressings and cooking as you use up the tomatoes.

    No waste here! (TIP: Amazon has good prices on olive oil here.)

    KEY for storage and safety:

    Make sure the tomatoes are completely covered in olive oil.

    7. Continue drying tomatoes, dipping, and covering with oil.

    When the next bunch of tomatoes are dry, just continue to "dip and drip" each one in the vinegar and place in the jar, covering the new additions with more olive oil.

    Jars of dried tomatoes in olive oil.

    8. When the jar is full, store it in a dark, cool place.

    As you use the tomatoes, just be sure the remaining tomatoes are fully covered before storing back on the shelf (you can add more oil if needed).

    How long do these dried tomatoes store on the shelf?

    The tomatoes are best used within a year. After about 6 months they will begin to darken and lose their redness, but are still safe to eat and flavorful after that, just not as pretty.

    Hopefully where you can reach it easily, because you will be using these a lot!

    How to Dry & Store Tomatoes In Olive Oil (at room temperature safely)

     Safely dry tomatoes and store them in olive oil at room temperature without canning. It's a great way to preserve tomatoes to use in any recipe calling for dried tomatoes.

    Course: Canning & Preserving
    Cuisine: American
    Yield: 1 quart
    Author: Jami Boys

    Equipment

    • Food Dryer (or use optional oven method)

    Ingredients

    • 3-5 pounds paste/plum tomatoes (preferably, though you can slice and dry bigger tomatoes)
    • 1/4 cup (or more) red wine vinegar (you can also use white wine vinegar or apple cider vinegar)
    • 2 cups olive oil, or enough needed to cover tomatoes

    Instructions

    • Wash tomatoes, cut the top core off and cut them in half.
    • Line the tomato halves on a dehydrator tray, cut side up.
    • Dry at the manufacturer's recommended 135 degrees.* Check at about four hours and then do the first switch: turn them over and turn the trays around. None are usually dry yet, except maybe a few really small ones. Let dry for another 1-2 hours before checking again. At this point, there will be some dry tomatoes and you'll need to remove these (I set them in a bowl) and continue drying the rest.
      Your fully dried tomato halves should be dry and leathery with no moisture coming out from them when you push them with your fingers
    • Fill a small bowl with red wine vinegar and using tongs, dip the fully dried tomato halves into the vinegar. Let the vinegar drip for a minute before placing in a clean, quart jar until the jar is full to the shoulders. It's okay to press down on the tomatoes to remove air and fit more into the jar.
    • Once a jar is full to the shoulders, pour olive oil over the tomatoes until they are FULLY covered. For safety, the tomatoes should always be completely covered with oil, even when you start using them. *You will need quite a bit of oil, but you will be able to use the oil for salad dressings and cooking as you use up the tomatoes.
    • Continue drying tomatoes, dipping, and covering with oil until all your dried tomatoes are used up.
    • Store jars in a cool, dark place for up to a year (they are best within 6 months, because they darken with time, but still safe to eat and flavorful after that, just not as red).

    Notes

    *Alternative oven-drying method:
    Cook tomato halves in a 170-degree oven for about 3 hours with the oven door left open about 3 inches for moisture to escape.

        It's to get most of the juice out so they dry faster and more evenly. I don't make sure all the seeds are off the tomatoes, just that the large seed-juice mass in the centers are gone. Does that make sense?

I put them in the fridge and am now seeing tiny yellow balls that look like cold oil, but I wanted to make sure I haven't mistepped by storing this in the fridge. Can you provide any insight for me please? Your help would be much appreciated. 🙂

        Yes, that's the olive oil hardening, as you guessed. It's perfectly safe to store them this way! The only downside is the solidifying oil that makes them a bit harder to use. But it does melt pretty quickly as you're cutting them for use in recipes, etc.

      It must just be that the vinegar is so acidic that it makes for an environment where botulism can't grow.

      • Jami says

        September 16, 2020 at 1:36 pm

        Well, as long as the tomatoes are dry and completely covered, botulism can't grow. I've stored these without the vinegar in the past and it's all good, they're just better with the vinegar.

      I understand that water and a no oxygen environment can cause Botulism. So drying is important. But if I then dip them in vinegar which is water based, aren’t I adding water to the mix?

        Bottled vinegar is a way to improve the taste and texture of the tomatoes. I have been storing tomatoes like this for many years and have never had a problem. I don't know all the chemical details, but perhaps the vinegar acts differently than pure water even though it has water as it's makeup?
        You don't use the vinegar rinse if you don't want to - it's up to you!

        Yes my question exactly. Vinegar is a water based thing. Chemically, it contains water. So would we not be adding water to the oil mix and risking botulism?

        Maybe if the tomatoes were soaked in vinegar before drying to make them more acidic but then the vinegar (and it’s water content) would be dried out.

          When vinegar is made, it becomes something different than pure water, so I'm assuming that's the difference.
          I've never had any issues in many years. That said, don't use the vinegar dip if you don't want to.

      Hi 🙂 we've done this a few times and I'm going a bit crazy as after about a week all the jars have popped (the button on top is up) and when we undo the jars it's bubbling and the tomatoes taste horrible and fizzy. Any ideas? It's happened with a few different batches with different olive oils, with or without vinegar... it's just such a waste and I would love any advice of where I'm going wrong!

      Thankyou 🙂

        Wow, as you can see from the video, that isn't my experience in all the years I've been making them!
        I'm wondering if you're not drying them enough? Is there any moisture that comes from the tomatoes when you press them?
        I have no other idea why that would happen - all the tomatoes are kept under the oil?
        I would not eat them for sure if there is any bubbling - that should not happen.
        Your other option is to refrigerate them after putting in oil to make sure you don't lose anymore. The olive oil will solidify some, but it's not that big a deal.

      So how long do they keep for? I've read you should keep them in fridge. Elsewhere is says freeze (but I think freezing glass not good). Some sites say use in a month..(which doesn't seem much like storage to me) but I still got a heap in the fridge so don't want to use for several months
      I don't see how storing in hot oil should hurt flavour..they've just been heated. Does this method enable them to keep longer?

        I've kept mine on the shelf for a year and while the tomatoes darken, they are still good. You can refrigerate if you feel better about it, but the oil will solidify. You don't want to heat the oil as it may "seal" under the lid (even without official canning) that would set up an anaerobic environment where botulism can grow.

      This is my third year of preparing tomatoes using your method. I did some tonight, and will let them sit for at least a month before opening them. This is the single thing I prepare at home, that really seems like a gourmet food. You simply cannot buy tomatoes like these in the store. Once summer is over, I no longer buy tomatoes, because they just are not good from the big producers. This is a great way of having a tomato treat in the winter. Thank you!

      Hi Jami!
      I came across your wonderful blog while googling how to store dried tomatoes. This year I am growing Principe de Bourghese tomatoes. They are a small pear type said to be excellent for drying. I've just begun drying the first batch and decided to try leaving them whole since they are so small. Can I still pack them in oil dried whole or must they be halved and seeded?

        Thank you for your sweet words, Katie! Hmmm, I'm not sure about the tomatoes - here's the issue, you have to be sure they are completely dry - no moisture spots while still pliable - and I'm not sure you can see that if they are whole. If you think you can, and believe they are totally dry, then go ahead. If you see any condensation within the first few days, you'll have to stick the jar in the fridge, though.

        They will last, Sandi, but the color won't be as bright as when you first make them. They darken over time. If you're okay with that, then it's all good. The people you give them to should use them within a couple months I'd suggest, as they will continue to darken (but like I think I mentioned, we've used ours a year later and while dark, the flavor is just as good!). They are also free to store in the fridge. 🙂

        It's never safe to can this, Lacee, as I state in the beginning of the article. Also adding either raw or roasted garlic introduces bacteria that builds (though more slowly) even in refrigeration, though they can last a few weeks. I really can't recommend adding anything but dried herbs/garlic to the tomatoes in oil.

        Here are the storage recommendations according to Oregon State University Extension Service:

        Raw or cooked garlic and/or herbs in oil:
        These mixtures MUST be refrigerated. Do not store them longer than 3 weeks in the refrigerator.

      I read on another website that its a good idea to add red wine to your dried tomatoes along with olive oil after you dip them in vinegar. They stated it added to the flavor. Would you recommend? I'm planning on freezing mine. Also, is it ok to use apple cider vinegar instead of red wine vinegar?

        Hmmm, I've never thought to do that so I can't really comment on the flavor or how it would affect shelf storage (though since you're planning to freeze, that is not an issue). And yes, you can use other vinegars for the dip - I'd just stay away from white vinegar since it's a little more stringent than red wine, apple cider, or other milder vinegars. Hope you enjoy these!

      Hi, I recently purchased a food dehydrator so I'm new to the process. I have a garden full of small pear tomatoes. I cut them in half, covered them lightly with olive oil and dried basil. Dried them in the food dehydrator and wanted to package for Christmas gifts.

          OK - I was reacting to your sentence -- "This tutorial for drying tomatoes and storing on the shelf in oil is how I’ve preserved and kept my dried tomatoes for years."

          I've noticed EVOL starting to go 'off' after 1,5-2 years. So was thinking about the 'YearS' that you wrote.

          I also grind the very dry tomatoes into a powder (with 'bean' grinder) - which has been great adding to sauces - I'll now see if immersing the powder into EVOL wouldn't add to its 'usability' possibilities.

          The powder - btw - seems to last INDEFINITELY

            I meant to say that I've been using cherry tomatoes - their smaller size allows the drying to be considerably faster - and also easier to use when ready. They have also been the tastiest - so tasty that so many get eaten before the 'process' begins.

            I've been drying them for years and they have been really great for kids - they call them 'tomato candy' - SO MUCH better than the sugar stuff. (Just 100% tomato).

              How about spraying ("mist") the red wine vinegar on the open faces of dried tomatoes while they are still on the drying pan? And even leaving the mist to dry.Would you think the 'effectiveness' would be 'good enough?' It sure would be easier.

      Jami;
      I've taken to using my dehydrator, too. When my tomato gems are ready to store I put them in freezer baggies, cover them with olive oil and freeze. They last forever. To keep them from getting any freezer burn I put a straw in the baggie when it's almost sealed all the way and I suck out any air in the bag and squeeze to finish the seal as I remove the straw. A WHOLE lot cheaper and easier than an electric vacuum sealer.

      The 'suck 'n seal' thing work great on steaks, all veggies and anything I want to last in the freezer.

I have a person in my canning group that stores hers for six months with no problems for the last ten years.

The dried tomatoes and oil I buy at the store are full of herbs and are delicious. After I open them I put them in the frig and they stay good for a long time.

        So happy you found AOC, Jerre! I can't say with certainty, but if you do it with the store-bought ones, I think they would last a similar length. At least a month or two. I would wait to mix in the herbs (if they're fresh - you can use dried herbs whenever) and garlic just before you will refrigerate them to be safe. The oil will solidify somewhat in the fridge, but you probably know that if you already store some there. 🙂

      Hi Jami,

      I've been looking all over the Internet for information about storing dried tomatoes and I'm glad I found your page. I started dehydrating 2 years ago, I haven't done much so I'm still a beginner. Recently, in a bowl I seasoned around 4 lbs of San Marzano tomatoes from my garden with around 1.5 tsp of olive oil and then sprinkled homegrown dried basil and salt on them. I dried the tomatoes with my Presto dehydrator then I put them in a canning jar with a plastic lid. Do I need to refrigerate the tomatoes for storage? The dried tomatoes are quite oily. I also have mylar bags that I seal with heat, I usually store dried veggies in the bags with oxygen absorbers in my pantry. I wanted to know the safety of storing tomatoes that have been seasoned with a little bit of oil inside jars or mylar bags in a cold dark place like my pantry. I'm hoping you could help me. I'm anxious about botulism, I don't want to poison my family. Thanks for your time! 🙂

        I don't know for sure, Priscilla, but I think it would be okay. That doesn't seem like a lot of olive oil, amazing they are "quite oily." The more important thing is that they are fully dried and that when you press on them no liquid or flesh comes out. They should be totally dry, leather and pliable. If they are that, I would think you're good to store them at room temperature. I would continually check them, though, for mold and spoilage. As long as there is even a bit of air in the storage containers, botulism isn't an issue since it needs an anaerobic environment to grow. Hope that helps!

The darken with age, but still are good so we don't mind. If you freeze them, they will collect moisture, so you can use them as dried tomatoes from the freezer, but you can't then put them in oil since the moisture could introduce botulism.:( Make sure to watch our video on this for more details!

      Great how-to, Jami! It's become next to impossible to find good sun dried tomatoes in other than toxic soy or canola oil so I have to make my own. Here are 3 more tips for extra flavour and shelf life:

      Squeeze a capsule of astaxanthin into each jar as this powerful anti-oxidant will easily triple the shelf life. It won't change the flavour but it will dye the oil red. You can still reuse the oil later for delicious salad dressings.

      To ensure you have all the air out of the oil you can use a vacuum pump. Even if you vacuum before sealing you'll at least know any air is out of the oil. A manual pump like Pump-n-Seal is one inexpensive option. Of course, vacuuming after sealing maximizes shelf life.

      While using fresh garlic or herbs is not advised, you can add a few drops of basil and/or garlic essential oils! With essential oils a little goes a long way. I always add a little basil oil to my olive oil for dressings and dips and just a touch to my homemade mayonnaise. It makes instant herbed oil!

      Thanks for the great article, but I have a question: is it okay to use a jar with a lid that snaps shut creating a seal? Here is a picture of the jar:

      http://www.ikea.com/us/en/catalog/products/90227985/

      Or does this create an air-tight environment that favors botulism growth?

      (Unfortunately, if it's not snapped shut, it doesn't close at all.)

        I'm pretty sure it's okay, as the lids I use are pretty airtight. We're not actually 'sealing' it with heat like canning, so as long as the tomatoes are completely covered, it should be fine.

          Actually, you really do need to get rid of the seeds. My first batch of tomatoes I dried with seeds in and they were SO crunchy. Not a good texture at all!

          I was really glad to find your recipe amidst all the "dry tomatoes to utterly crisp to store on the shelf" and "if you cover with olive oil, you must store in the fridge" that abounds. Surely generations of Italian Nonne could not be so very, very wrong.

          The panic around this simple and safe storage method (and the discussion of the wire-and-bail seals) reminded me of trying to find instructions on how to use the Crown jar 3-piece lids (rubber ring, glass lid, zinc ring) that my grandmother used to use. I found site after site saying "just don't", which is silly; they're easier to use than Tattler lids and just as safe. Bit of a learning curve, but when you've used up all the regular Ball jars, it's a life-saver.

            We don't notice the seeds at all dried like this and stored in olive oil - I guess that's when personal preference come in to play. 🙂 I try to strike a balance between current safety and time-honored techniques (and err on the safe side) by really researching where the issue lies. In this case the origin of the warning didn't pan out, thankfully since we love them this way!

      Hi! Thanks for the post, I have too many tomatoes and thought preserving then in oil for Christmas gifts would be nice. I have two questions:
      1. Maybe I missed something here, but from what IU read you just dip in vinegar, put them in the jar and cover with oil...then it goes in the cupboard? Is there any actual canning process done?
      2. If you aren't following a full canning process (like with submerging in boiling water and all that), how long does you product last?

      I'm not for or against any particular method, but I am trying to figure that best way to go about this. I was thinking of doing a preserved dried tomato in olive oil with garlic and fresh herbs. If not properly canned, I think this would spoil. Do you have any recommendations?

      Thanks!

        Hi Chris! I've tried to emphasize that it's never okay to add any type of fresh herbs or garlic (or anything fresh) to olive oil - even as a homemade infusion without the tomatoes - and keep it on the shelf, canned or not. There's no way to do it safely at home, sorry! You'd have to keep in in the fridge and then only for a few months.

        This recipe is to keep tomatoes, and only tomatoes, submerged in olive oil on the shelf. You could add some dried herbs, but that's it. It is not a canned recipe - that would actually make it dangerous, as that would remove the air and make the perfect environment for botulism.

        This lasts for us for a year, but the tomatoes darken after about 6 months. We don't find the flavor is affected, just the color. I hope this answers your questions!!

      I put up four small bottle of dried tomatoes in olive oil, as described. I've done this for years, except did not vinegar wash them until I read this. I also put them in the fridge. First time ever, one bottle is fermenting! It's in the fridge and it's giving off bubbles. I've watched in a while and it truly is fermenting.

      It doesn't smell bad at all so my guess is that this is just lactobacillus, and it's probably perfectly ok. It actually might even be really good! However, I have no intent to find out. They are going in the garbage. Heartbreaking.

      I think the lesson is that despite all your work, sometimes things fail. Just get over it and learn. I think I will be more particular about which tomatoes I use and step up the washing and rinsing.

          I did 2 large jars of these tomatoes this year for the first time and both fermented as Matt described. Bubbles came up from the bottom of the jar. Truly heartbreaking to throw them away as they were our go to on a daily basis. I followed the directions meticulously and dipped in vinegar as well. Next year I will dry longer, pat dry before covering with oil and be sure that there's a good inch of oil on top.

Originally from Holland my family never "processed" pickles either. They were put in vinegar with spices and merely covered with a topping of "salad" oil (I use Canola). works great too.

        The jars aren't sealed, Susan, in any other way besides screwing them on - the olive oil is providing the 'seal' to the tomatoes in this case. The storage is the same whether the jar has been opened previously - 6 months ideal, but we use them up to a year later. They are darker and not as pretty, but give all the great flavor, still. 🙂

Adding anything fresh introduces moisture and the chance for botulism, so you'll need to refrigerate if it is fresh rosemary (and some sources say even with refrigeration you should be careful!). I'm hoping you used dried, though! 🙂

      There was a discussion about this on the Harvest forum and this reference was cited, your method uses just vinegar, even better. "THE U. C. DAVIS METHOD FOR PACKING DRIED TOMATOES IN OIL
      If you’d like to pack dried tomatoes in oil, follow these steps:
      After the tomatoes are dried, it is recommended that you place them in a bowl and sprinkle with diluted (one part vinegar, one part water) distilled white vinegar. This acidifies the tomatoes and also adds back some moisture, for a chewy texture.
      Empty bowl onto paper towels and pat tomatoes dry.
      Pack tomatoes lightly into clean pint or half-pint jars. At this stage you may add herbs or spices, dried only. Cover with oil
      to ½ inch of the rim of the jar. At room temperature, oil may become rancid. This is not unsafe, but undesirable. If garlic is
      desired, U.C. Davis recommends acidification of the garlic by marinating with fresh herbs and vinegar 24 hours, checking to
      see if vinegar has completely penetrated before putting in oil."
      What brand is your dehydrator, I have an old Montgomery Ward(!) one but the trays look just like yours pictured.
      I have really enjoyed your recipes, the green beans with garlic--YUM.
