Red pepper flakes, also known as crushed red pepper, are made from dried and crushed whole red chili peppers—including the seeds, which contribute to its heat. This spice is renowned for its ability to deliver a consistent, fiery flavor with a slightly fruity undertone, making it a favorite for sprinkling over pizza, pasta dishes, and stir-fries. Red pepper flakes are versatile and can be used in cooking or as a garnish to add a bit of spice to any dish.
