Anyone make their own Mexican seasoning?

Not Mexican per se, but I smoke peppers, dry them in the oven, and then grind them up to use as chili powder in southwest-inspired dishes.

For tacos I usually use a mix of cumin and chili powder plus whatever else I have on hand that looks good at the moment. Usually red pepper, garlic powder, black pepper, and maybe some cayenne. I very much eyeball/smell/taste test it.

My wife uses this for tacos. Its better than any of the store bought packets of taco seasoning. It doesn't look like enough salt, but is comes out great.
