Gochugaru, or Korean red pepper powder, has a smokey, fruity-sweet aroma with a spicy sting. The pepper is best recognised for being used in the country's national cuisine, kimchi. One of the most important Korean cuisine ingredients is gochugaru. Gochujang (Korean chili paste), Kimchi, hot Korean soups and stews (such as Sundubu Jjaigae), and spicy Korean side dishes all contain it (e. g. Korean spicy cucumber salad).
