1 quart tomato sauce
1 T cumin
2 poblano peppers
2 jalapeño peppers
1 large onion, roughly chopped
3 cloves garlic, lightly crushed
4 T sugar
1 T kosher salt
2 dried ancho chilies, seeded and chopped into 1 inch pieces
1 1/2 t lime juice
1/4 c white vinegar
Using the recipe in the link above, make tomato sauce. Work through step 4, reducing by a third for a thinner sauce. If you want to break this process up, make the tomato sauce the day before and refrigerate overnight.
Bring tomato sauce to a boil in a large stainless steel, enameled or nonstick pot. After 2 minutes, reduce to a simmer.
Preheat broiler. Place peppers, onions and garlic in a single layer in a 15x10x1 inch baking pan. Broil 3 to 4 inches from the heat for 8 to 10 minutes rotating peppers until skins are lightly charred on all sides. Move charred peppers to a paper bag or covered dish and allow to steam for 10-15 minutes. Add onions and garlic to simmering tomato sauce.
Once peppers have cooled, remove skins, seed and chop. Add peppers to tomato sauce. Add sugar, salt, and dried chilies to tomato sauce. Stir to combine. Increase heat and return to a boil, stirring frequently for 2 minutes. Reduce heat and simmer, uncovered, for 30 minutes.
Using an immersion blender, process until smooth. Strain mixture through a fine-mesh sieve, pushing liquid through and scraping the inside of the sieve with a rubber spatula, discard solids. Return strained mixture to the large pot. Bring to a boil, reduce heat. Simmer sauce, uncovered, about 10 minutes or until slightly thickened and reduced to about 4 cups. Stir in lime juice and vinegar.
Ladle hot sauce into hot, sterilized half pint jars, leaving a 1/4 inch headspace. Wipe jar rims, adjust lids. Processed filled jars in water bath canner for 35 minutes (start timing when water returns to a boil). Remove jars and cool overnight. Makes 5 half pints.
