Cayenne pepper is a fiery spice made from finely ground dried chili peppers, known for its bright red color and pungent heat. It adds a spicy kick and a subtle earthy flavor to dishes, with a smooth, slightly gritty texture. Widely used in cuisines around the world, notably in Mexican, Indian, and Cajun cooking, it enhances the flavor profile of sauces, stews, and marinades. Historically, cayenne has been valued for both its culinary and medicinal properties, with origins tracing back to the indigenous peoples of the Americas long before European contact.
