Combine all ingredients until smooth in a saucepan.
Bring to a boil, reduce heat to low and simmer 15-20 minutes (you'll need to partially cover because it will spit hot tomato out at even the lowest simmer). If it seems too thick, add water, a teaspoon at a time to desired consistency.
Let cool and then pour into a glass bottle for storage (a metal funnel makes this easier).
Keep refrigerated. If it thickens too much in the fridge, just add some water (a couple teaspoons at a time) to reach pouring consistency.
*This is the amount I always make for our family, though it does make a lot. If you need less, cut everything down by half - and yes, that would be only 3 tablespoons to 1/4 cup of sweetener for the half batch!**If you're trying to wean off of super sweet store-bought, start with the higher amount of honey, then see if you can go down to the lower amount later.
