If you prefer to buy cayenne pepper locally, the answer is usually pretty easy – your local supermarket. Cayenne pepper is common enough that nearly any supermarket or grocery store should carry it, at least in its powdered form. Check the spices aisle. For dried cayenne peppers, they are also often found in the spice/cooking aisle as well, but if you don’t see it there, the produce aisle may be the place. If your regular grocery store doesn’t stock dried cayenne pepper, try someplace like Whole Foods or an ethnic market. Look for fresh cayenne peppers in your produce section. For capsaicin cream, check the health and pain relievers aisle. Most of the cayenne ointments will be in the arthritis pain relief section.
