Korean Red Hot Chili
Although Korean cuisine offers a host of great non-spicy dishes, it is famous for its fiery spiciness. But what is the secret to the spice? The spicy taste of many Korean foods largely comes down to one key ingredient: gochugaru (red chili flakes or red pepper powder). Gochugaru is made by drying Korean red chili peppers in the sun, de-seeding them and crushing them into flakes.
Interestingly, red chili pepper was adopted by Koreans not too long ago (late 16th century), totally shifting the paradigm of Korean cuisine from that time forth. Today, gochugaru (Korean Hot Pepper Flakes or Korean Red Chili Flakes) is one of most essential ingredients in Korean cooking. It simply cannot be replaced with chili flakes or sauces from other places when it comes to cooking authentic Korean food. Korean hot pepper flakes are usually a vibrant red, coarse in texture and fairly spicy in taste, with a hint of sweetness. How they rate on the spiciness meter can vary depending on the region of origin and its specific farming conditions.
There are two types of gochugaru that Koreans use: fine powder and flakes.
