I have been trying for years to make a good red enchilada sauce. I have finally accomplished it!
1 teaspoon olive oil
1 tablespoon good quality chili powder
1 15 oz can tomato sauce
1 tablespoon chipotle chile en adobo sauce or chipotle salsa (found in the ethnic section of most US grocery stores)
Using a medium saucepan, heat oil over medium, add chili powder to bloom in oil for 30 seconds. Add tomato sauce, then chipotle. Reduce heat to a bare simmer. Let simmer 10 minutes, then use to top enchiladas, burritos, or anything else you want. Taste for seasoning, add salt or pepper as needed.
