Introduction to Gochgaru
Gochgaru (고춧가루), also known as Korean red chili pepper flakes, is the essential spice behind Korea's most iconic dishes. Made from sun-dried red chili peppers ground into a fine powder, it delivers a unique balance of moderate heat, natural sweetness, and subtle smokiness. Unlike generic chili powders, authentic gochgaru is a cornerstone of Korean cuisine with specific culinary applications that cannot be replicated by substitutes.

What is Gochgaru?
Gochgaru is produced from specific Korean chili varieties like Hwangkeumcho or Cheongyang peppers. After harvesting, peppers are sun-dried for 7-10 days, then stone-ground to preserve natural oils and vibrant color. Authentic gochgaru contains only chili peppers and minimal salt (typically 0.5-1%), with no additives or fillers. Its distinctive characteristics include:
- Heat level: 3,000-5,000 Scoville Heat Units (SHU)
- Color: Deep crimson red (retains vibrancy when stored properly)
- Texture: Fine to medium grind (coarse for rubs, fine for sauces)
- Flavor profile: Sweet, smoky, with subtle fruitiness

Gochgaru vs. Other Chili Powders
Chili Powder | Heat Level (SHU) | Flavor Profile | Best Uses |
---|---|---|---|
Gochgaru | 3,000-5,000 | Smoky, sweet, slightly tangy | Kimchi, tteokbokki, buldak, Korean stews |
Cayenne | 30,000-50,000 | Sharp, fiery, one-dimensional heat | Hot sauces, spice blends, Mexican dishes |
Paprika | 100-1,000 | Mild, sweet, earthy | Spanish paella, Hungarian goulash, seasoning rubs |
Ancho | 1,000-1,500 | Dried fruit, raisin-like, mild heat | Mole sauces, Mexican stews, adobo |

Flavor Profile of Gochgaru
Authentic gochgaru offers a complex flavor profile that sets it apart from other chili powders:
- Sweetness: Natural sugar content from ripe chili peppers creates balanced heat
- Smokiness: Sun-drying process imparts subtle woodsy notes
- Fruitiness: Distinct berry-like undertones from Korean chili varieties
- Umami: Develops deeper savory notes when cooked with fats or fermented ingredients
Quality variations: High-grade gochgaru (made from first-harvest peppers) has brighter red color and sweeter profile, while standard grade may have more heat and earthiness. Always check for "1st grade" or "premium" labeling for best results.

How to Use Gochgaru in Cooking
Proper technique maximizes gochgaru's flavor potential:
- Toast for depth: Dry-toast in a pan for 30 seconds before adding to sauces to enhance smokiness
- Combine with fats: Mix with sesame oil or gochujang for better flavor distribution
- Layer during cooking: Add early for base flavor (stews), later for fresh heat (stir-fries)
- Use with fermentation: Essential for kimchi (10-20% of total weight) and fermented sauces
- Control heat: Start with 1 tsp per 2 cups of liquid, adjust to taste

Frequently Asked Questions (FAQ)
What is gochgaru?
Gochgaru (고춧가루) is Korean red chili pepper flakes made from sun-dried Korean chili peppers. It's the essential ingredient in kimchi, tteokbokki, and gochujang, providing distinctive smoky-sweet heat rather than pure spiciness.
Is gochgaru the same as gochugaru?
Yes. "Gochugaru" is the standard Romanization of 고춧가루, while "gochgaru" is a common alternative spelling. Both refer to the same Korean chili powder.
How spicy is gochgaru?
Typically 3,000-5,000 Scoville Heat Units (SHU), making it milder than cayenne (30,000-50,000 SHU) but hotter than paprika. Its heat is balanced by natural sweetness and smokiness.
What can I use instead of gochgaru?
For authentic flavor, no perfect substitute exists. For emergencies: mix 8 parts sweet paprika + 1 part cayenne. Avoid regular crushed red pepper - it's too hot and lacks gochgaru's signature sweetness.
How should I store gochgaru?
Store in an airtight container in a cool, dark place. For maximum freshness (beyond 3 months), refrigerate or freeze. Proper storage preserves color and flavor for up to 1 year.
Is gochgaru the same as gochujang?
No. Gochujang is a fermented chili paste made with gochgaru, glutinous rice, soybeans, and sugar. Gochgaru is simply dried, ground chili peppers without fermentation.
Why is my gochgaru not as red as in pictures?
Authentic gochgaru loses vibrancy over time. Exposure to light, heat, or air causes color degradation. For brightest color, purchase small quantities and store properly. Some brands add artificial colorants - true quality comes from natural pepper pigments.
Can I make my own gochgaru at home?
Yes. Dry Korean red chili peppers completely (sun-dry for 7-10 days or use dehydrator), then grind to desired texture. Use a high-powered blender for fine powder. Homemade gochgaru may vary in heat and color based on pepper variety and drying conditions.
