Before you embark on your next grocery shopping trip to stock up for that big pot of chili you've been craving, note that chili powder is not the same as chile powder. Chile powder consists purely of dried and ground chile peppers, while chili powder is a combination of ground dried chiles, oregano, cumin, garlic and salt.
Uses
Chili powder is most commonly used to season chili. It also shows up in enchiladas, spice rubs, and other Mexican and Tex-Mex dishes.
