What does cayenne pepper taste like?

Cayenne pepper has a pungent and spicy flavor with a slight smoky undertone. It is widely used as a spice to add heat to dishes, sauces, and marinades. The spicy kick in cayenne pepper comes from the presence of capsaicin, a compound found in chili peppers that activates the TRPV1 receptors in the mouth, giving it the sensation of heat. The intensity of the spiciness can vary depending on the variety of chili used and the amount of pepper added. Cayenne pepper is often used in small quantities to add warmth and a subtle spiciness to food.
