1. Combine the chiles, garlic, onion, brown sugar, and 1 quart water in a large saucepan and bring to a boil over high heat. Reduce the heat and simmer until the chiles are very soft, about 30 minutes.
2. Transfer the solids to a food processor using a slotted spoon and add 1 cup of the cooking liquid. Process until smooth, adding more of the cooking liquid to reach a thick but pourable sauce consistency. Season the sauce with the honey, vinegar, and salt and pepper to taste. The sauce can be refrigerated for up to 1 day. Reheat before serving. |
