My sister-in-law was born and raised in Mexico City. She taught me how to make these. They take some time, but for those of us who love to cook and enjoy the fruits of our labor - this will be a real treat. You will need a blender or food processor for the sauce. This recipe makes 24 enchiladas. Enough for a crowd, or to freeze. If you are going to take this much time, you may as well have plenty! It can be halved, if you prefer. The sauce and stuffing can be prepared in advance.
