Dry red chilies are the dried, ripened fruits of the chili pepper plant, prized for their concentrated heat and complex flavor. The level of heat comes from capsaicin and varies by variety. A staple in many cuisines, they are used whole, crushed, or ground to add a spicy kick to curries, sauces, and spice blends. Beyond their use as a spice, they also offer health benefits, including boosting metabolism and aiding digestion.
