Korean chili peppers — most commonly known as gochugaru — are one of the most misunderstood ingredients in the spicy food world. They look fiery, but they’re not brutal. They taste complex, but not overwhelming. And they’re the backbone of some of the most iconic Korean dishes on the planet.
This complete guide explains Korean chili peppers (gochugaru) in detail: what they are, how hot they really are, how they taste, how they differ from other chili flakes, and the best ways to use them in cooking and sauces.
What Are Korean Chili Peppers (Gochugaru)?

It’s made from:

Korean red chili peppers (gochu)

Seeds partially removed
-
Ground into coarse flakes or fine powder
Unlike Western chili powders, gochugaru is:

Pure chili (no cumin, garlic, or fillers)
-
Mild to medium in heat
-
Naturally sweet and smoky
🔥 Gochugaru is essential to Korean cuisine — not optional.

Gochugaru typically ranges between:
4,000–8,000 Scoville Heat Units (SHU)
