Cayenne pepper is a hot chili in the Capsicum family. People frequently use it to enhance the flavor of savory dishes, and nutrients in the pepper may provide health benefits.

Cayenne peppers are closely related to jalapeño and bell peppers. They are a staple in Southwestern American, Mexican, Cajun, and Creole cuisine. Dried and ground, they make a powdered spice for seasoning and also feature whole in Korean, Sichuan, and other Asian cuisines.
