Cayenne pepper is a hot chili pepper used to add heat and a pungent depth to dishes and drinks. In the context of cocktails, cayenne is often used sparingly to imbue beverages with a warm, spicy kick. It can be incorporated in several ways, such as part of a rimming salt for bloody marys, sprinkled over a drink for enhanced flavor and aroma, or infused directly into a spirit or syrup to create a fiery component. Cayenne pairs well with chocolate and citrus flavors, making it a versatile ingredient for adding an unexpected twist to both alcoholic and non-alcoholic concoctions.
