Chili flakes, also known as red pepper flakes, are made from dried and crushed red chili peppers. They are used to add heat and a spicy flavor to a variety of dishes, including pizzas, pasta, soups, stews, and sauces. They can also be used as a condiment, and are often served in shakers on tables in pizza parlors and Italian restaurants.

Chili flakes are a good source of capsaicin, a compound that gives chili peppers their heat and is also believed to have anti-inflammatory and pain-relieving properties. They are also high in vitamin C and other antioxidants.

The heat level of chili flakes can vary depending on the type of pepper used, so it’s important to taste a small amount before adding it to a dish to gauge the level of heat. Some common chili flakes include cayenne pepper flakes, which are made from cayenne peppers and are quite spicy, and crushed red pepper flakes, which are a blend of different types of peppers and may have a milder heat level.
