Ingredients
2 tablespoons canola oil
1 large Spanish onion, coarsely chopped
5 cloves garlic, coarsely chopped
3 cups canned plum tomatoes and juices, pureed
1 cup water
1/4 cup ketchup
1/4 cup red wine vinegar
1/4 cup Worcestershire sauce
3 tablespoons Dijon mustard
3 tablespoons dark brown sugar
2 tablespoon honey
1/4 cup molasses
3 tablespoons ancho chili powder
3 tablespoons pasilla chili powder
2 to 4 canned chipotle chiles in adobo, pureed (depending on how spicy you like it)
Salt
Freshly ground black pepper
Preparation
Heat the oil over medium-high heat in a heavy-bottomed medium saucepan. Add the onions and cook until soft, 3 to 4 minutes. Add the garlic and cook for 1 minute. Add the tomatoes and water, bring to a boil and simmer for 10 minutes. Add the remaining ingredients and simmer for an additional 30 to 40 minutes until thickened, stirring occasionally.
Transfer the mixture to a food processor and puree until smooth, season with salt and pepper, to taste. Pour into a bowl and allow to cool at room temperature. Sauce will keep for 1 week in the refrigerator stored in a tightly sealed container
