Ancho chili flakes are made from dried and crushed ancho chilies, which are the dried version of the poblano pepper. These flakes have a deep, smoky, and mildly sweet flavor with a subtle heat level. The heat intensity can vary, but generally, they are considered to have a mild to moderate heat compared to other chili varieties. Ancho chili flakes are often used in Mexican and Southwestern cuisine to add depth to sauces, stews, soups, and marinades. Their rich, earthy flavor pairs well with chocolate, tomatoes, and other bold spices, making them a versatile ingredient for both savory and sweet dishes.
