Question: are red pepper flakes hot?
Answer: Crushed Red Pepper is a must in every kitchen (and on every pizzaria table in the U.S.). These chiles are about a 3 to 4 on a heat scale of 1 to 10 and add a pleasant note of heat to any dish. Red pepper flakes are not made of one type of chile, but from various combinations of ancho, bell, cayenne and more.
