The first steps - take two large roasts and cover with water. Add garlic, salt and pepper - bring to a boil and then simmer covered for several hours until the meat is tender. You will probably have to add water to keep the meat covered and to prevent it drying out. Once the meat is cooked, drain off the liquid, let the meat cool and shred into bite sized pieces.
This is what the meat will look like
Next place a large bag of dried chile pods -( this is what the label on the bag we used looked like)
Cover with water, bring to a boil and simmer covered for several hours (about two) until the chiles are tender. The chiles will begin to "cook down", just add hot water as needed so they don't dry out or burn. There are many different kinds of dried chiles and I am sure their are personal preferences as to which you will choose to use - The ones we used are the "Chile California"
This "chile rojo" (red chile) can be used for enchiladas, chile colorado and many other dishes.
Next is getting the corn masa ready to use. You can purchase "masa preparada" in the Mexican grocery. We had 10 lbs of masa to work with. Let it come to room temperature before you begin to work with it. After you have the consistency you want you will add the red chile little by little
