I live in southern New Mexico. Our cuisine is far different than that of northern New Mexico (ie, Santa Fe, Taos, etc.). Las Cruces, or Hatch really, is the chile growing capital of the world. Whenever we have pot lucks at work or partys, my green chile enchiladas are always requested. If it is going to be an especially large group, I leave out the chicken and just make several trays of green chile cheese enchiladas.
Just for clarification, "CHILI' is that soup dish made with hamburger meat and beans that is popular in Texas, while "CHILE" is the spicy vegitable that makes mexican food so great.
Green chile and red chile come from the same plant. Green chile is harvested when ripe, and red chile is from chile left on the vine or tied up in RISTRAS to dry out and become red chile.
When I was in college in Odessa, they didn't have descent green chile, they used tomatillos instead. I did not like that at all, so I substituted fresh jalapenos instead. They were hot, but my west Texas buddies ate them all up (of course sweating out the jalapenos the whole time).
