This sauce is delicious with the chiles rellenos, but would also be perfect drizzled over enchiladas or added to your favorite chili.

Preparation
Step 1
Stem and seed chiles; tear into 1-inch pieces. Heat heavy large skillet over medium heat. Add chiles to dry skillet and toast until beginning to smoke, stirring occasionally, 5 to 6 minutes. Add 2 cups water; bring to boil. Remove from heat and let stand 20 minutes to soften. Drain.
Step 2
Stir cumin seeds in small skillet over medium-high heat until slightly darker and aromatic, 3 to 4 minutes. Cool. Transfer to spice mill; process until finely ground.
Step 3
Heat oil in heavy medium saucepan over medium heat. Add onion; sauté until golden, stirring often, about 8 minutes. Add garlic, oregano, and ground cumin. Add drained chiles and 1/2 cup broth; sprinkle with salt. Bring to boil; reduce heat to medium-low, cover, and simmer 20 minutes to allow flavors to blend. Add 1/2 cup broth.
Step 4
Working in batches, purée sauce in blender until smooth. Add vinegar and sugar. Season with salt and pepper.
