Don't really follow a recipe...this is a very forgiving product to make.
destem, put in oven @ 425F for 2-4 minutes (keep an eye on them so they don't scorch), grind to flake consistency in food processor, grind to powder in coffee grinder, store in coldest part of freezer to preserve. I use about 1C per 3lbs of chuck roast (2" cubes, no ground meat here).
If you are making a large batch, go easy on the hot peppers (like arbol and chipotle) so you have more flexibility when you actually use the product later on.
