Shishito sweet pepper is a long-time favorite variety in Japanese markets. The shishito chile matures from a lime green to a dark red colored exterior that is wrinkled and narrow in shape. These 3"-4" long peppers with wrinkled skin are used in tempura, yakitori or stir-fries. High in vitamins A and C, these peppers are hotter than bell peppers, but not as hot as chili peppers. The mildly flavored flesh is very good for tempura. It is a chile that is commonly served in salads or pickled and served as a condiment.
