Ingredients
6 ancho chiles
1 cup diced white onion
2 garlic cloves
1 cup water
Coarse salt and ground pepper
1 tablespoon vegetable oil
1/4 cup minced golden raisins
1 cup low-sodium chicken broth
1 teaspoon white vinegar
Pinch of sugar
Preparation
In a medium bowl, cover chiles with boiling water. Let stand until softened, 15 minutes. Drain, stem, and seed chiles, then transfer to a blender with onion, garlic, and water. Puree until smooth. Season with salt and pepper. Pour through a fine-mesh sieve and discard solids. In a medium pot, heat oil over high until shimmering. Add chile mixture, raisins, and broth and simmer, stirring occasionally, until thickened, 5 to 10 minutes. Remove from heat and stir in vinegar and sugar. Season to taste with salt and pepper.
