Red chili flakes are crushed dried red chilies that offer a bold, spicy heat with a slightly smoky flavor. They are commonly used to add a kick to pizzas, pastas, soups, and marinades, providing a quick burst of heat without overpowering other flavors. Versatile and easy to use, red chili flakes can be sprinkled directly onto dishes or incorporated into spice blends to enhance a wide range of recipes with their vibrant, fiery essence.
