Gochugaru

Korean dried red pepper flakes made from the red, ripened form of Korean chile peppers. They are fully ripened on the plant, sun-dried and seeded, then ground into coarse or fine pepper. (Gochu means “chile pepper,” and garu means “powder.”) I use coarse flakes for kimchi and finer for things like banchan. It comes in many different levels of heat; check the intensity of yours before you use it. Store this long-term in the freezer, and use it within a year.
