Mix all ingredients in a bowl, then use as a seasoning or a rub.
Notes
Choose your chili powder and the amount of cayenne used wisely. The combo can make this chili lime seasoning surprisingly hot. For very mild heat, opt for generic paprika or ancho powder with little to no additional cayenne. Choose smoked paprika, for a smokier flavor.For medium heat, guajillo powder or chipotle powder both work (chipotle being smokier and slightly hotter.)
