In older Spice Trade definitions, when a pepper was unusually hot it was called "cayenne" -- whether or not it actually was grown in the Cayenne region of South America. These are also known as “hot red pepper” or just “red pepper,” and cayenne is often used not just for the heat but for its ability to subtly enhance other flavors. Cayenne pepper ranges from 35,000 to 70,000 Scoville heat units. This organically sourced cayenne pepper will add a nice zip to any dish – and we also carry conventionally grown cayenne pepper.
