Dried peppers can be used whole, crushed, or powdered. Whole peppers can be added to soups or stews and will rehydrate during cooking. As they rehydrate they infuse flavor into the liquid. Remove the stems and seeds first, and toast the peppers quickly in a pan before adding them for the best results. Dried peppers with the stems and seeds removed can also be crushed in a food processor or turned into powder by using a spice grinder. Mix your own blend of peppers for the heat level you prefer. Use the flakes or powder in dry rubs, sauces, seasonings, toppings, and even sprinkled on eggs or pizza.
