Ingredients
Method
- Toast dried chiles in a dry skillet for 30 seconds per side, then soak in hot water for 15–20 minutes.
- Melt butter in a saucepan and whisk in flour to make a light golden roux (about 2–3 minutes).
- Blend soaked chiles with chili powder, garlic, cumin, oregano, tomato paste, and broth until smooth.
- Slowly pour the blended mixture into the roux, whisking well, and simmer for 15 minutes until thickened.
- Stir in salt and vinegar, adjust to taste, and strain the sauce if a smoother texture is desired.
