Dried peppers are fresh peppers that have had their moisture removed, resulting in a concentrated flavor and longer shelf life. Common varieties include jalapeño, ancho, and cayenne. They can be used whole, crushed, or ground into powder, adding heat and depth to various dishes. The drying process can be done through sun-drying, air-drying, or using a dehydrator. Dried peppers are often used in cuisines around the world, such as Mexican and Indian cooking, to enhance sauces, soups, and marinades. They are also a key ingredient in spice blends like chili powder.
