Finish enchilada sauce: in a
blender, process the hydrated peppers with broth they were soaked in. Plus, garlic, Mexican oregano, black pepper and cumin until completely broken down and smooth.
Strain. Add 1/2 cup of broth into the blender, swirl to get the last bit of sauce, and strain. The sauce should have body, run loosely, be smooth, and coat a tortilla nicely. If too thick, feel free to add more broth or water until you reach the right consistency. Mix in salt the salt. Set aside momentarily.
