Hot Chili Peppers… gave their intensity when ingested with capsaicin and several related chemicals. When consumed capsaicin bind with pain receptors in the mouth and throat responsible for sensing heat. Once activated by capsaicin, the receptors send a message to the brain that person has consumed something very very hot. The brain responds to the burning sensation by raising the heart rate, increasing perspiration and releasing endorphins. Dried chili peppers are often ground into powders. Dried whole chiles may be reconstituted before grinding to a paste used to flavor soups and stews with bean paste. The leaves of the chili plant, mildly bitter and nowhere near as hot as the fruit, are often pickled with kimchi. Local markets are never without peppers, stocked well in various sizes, in fresh and dried form. Hot sauces and stews found in many foods are made with gochujang paste.
