Heat the tomatoes, onion and garlic until soft. Puree in blender. Put back into wide bottom pot. Combine the rest of the ingredients in the pot and simmer until reduced by half. [You can do this in a crock pot.] Adjust spices to taste. Makes 6 1/2 cups.

Notes:
Blackberry juice: Cook the blackberries with a bit of water [so they don’t stick to the pot]. Mash. Strain seeds and skins out. I line my chinois [colander, sieve, strainer] with cheesecloth, put the mash in, and squeeze the juice out.

Consistency: We like it on the thin side. If you want it thicker, cook it longer.

You can halve the recipe if you need to.
