Thanks for starting this thred. My parents and 8 siblings are all from El Paso. In fact, every "Adauto" in the phone book is a relative.
My sister, wife and I made 5 dozen green chile, pork and cheese tamales last week. They are in the freezer until tomorrow night when we will steam them. Ours are made very similar to the way you described them. This year, I roasted a 30 pound box of Hatch, NM chilies, so they will be real hot. Can't wait.
