CrockerDAD, you are missing out not having an HEB in El Paso. Hell, anyone other than Albertson's or Walmart. Was there for Father's Day and Albertson's wanted $8 for the larger size of Heinz 57.
And fortunately, we have the 'connection' that gets Hatch chile delivered to SA (in exchange for a few days with the grandkid).
The red, dried chile off a ristra can be boiled, peeled, and stuck in a blender. Add some water and you'll get a paste. Strain that through a wire mesh strainer. Add onion, garlic, etc., or a little tomato sauce if it is too hot. In addition to enchilada sauce, you can add it to a roast to make chile colorado con carne.
You can also take the Hatch green chile, roast, peel, blend, strain, and add to sour cream, heavy cream, or even queso fresco to make green enchilada sauce. It's the shiznit with chicken.
Damn, now I'm hungry.
