Measure all of the individual spices and pour them into a bowl.
Stir the spices together to combine.
Store in a glass jar or zipper topped bag.
Notes
Chili powder is actually a blend of dried chiles and other spices, so it would be best not to substitute with straight ancho or chipotle powders. You could always add them if you like.
This recipe makes approximately 10 tablespoons spice mix.
