As long as you are an expert in Southwest cooking, can you help out with a good formula for chili powder>?
I keep trying various combinations of cumin. paprika, garlic powder, turmeric, ceyanne pepper, salt and fine grind pepper. Some combinations are better than other but none is really great.
I have learned to leave out coriander and Mexican oregano as they both taste a bit like dried powdered lawn clippings.
