Red Pepper Flakes (Gochugaru)
Capsicum annuum (dried, ground)
Chili peppers arrived in Korea from the Americas via Portuguese and Japanese trade routes in the 16th-17th century. Despite being a relatively recent addition to Korean cuisine, gochugaru became so thoroughly integrated that it is now considered essential to Korean identity. The Donguibogam's later editions reference chili's hot nature and spicy flavor. Korean sun-dried gochugaru has a unique character — fruity, mildly sweet, and complexly smoky — that distinguishes it from chili flakes of other cuisines. The traditional practice of families sun-drying their own peppers and grinding them fresh each autumn persists in rural Korea.

Seasonal Availability
Red peppers are harvested in late summer/early autumn and sun-dried. Freshly ground autumn gochugaru has the brightest color and most vibrant flavor. The Cheongyang and Yeongyang regions produce the most prized varieties.
Processing Methods (법제)
Sun-drying concentrates capsaicin and develops color. Coarse grinding (굵은 고추가루) preserves texture for kimchi; fine grinding (고운 고추가루) is for sauces.
Consumption Tips by Health Goal

Add to warming soups and stews in winter. The capsaicin promotes sweating and warms the body from the core outward.
