What Is Gochujang, Anyway?
Gochujang (고추장) literally translates to "red chili paste," but that barely scratches the surface. Unlike basic chili pastes, gochujang is deeply fermented using meju (fermented soybean blocks), red chili powder, glutinous rice, and salt. The fermentation process, which can take anywhere from several months to years, gives gochujang its signature complexity: sweet, salty, spicy, and umami-rich.

Why Make It at Home?
Sure, you can buy gochujang at the store, but there's something incredibly satisfying about making your own version from scratch. Here’s why you should try:
- Fresher flavor: No preservatives or additives.
- Customization: Control the spice level, sweetness, and texture.
- Cheaper long-term: Especially if you're a regular user.
- Talk about bragging rights: “I made my own gochujang” earns serious kitchen street cred.
Ingredients You’ll Need
You don’t need a lab coat to make gochujang, but you do need these essential ingredients:
Ingredient | Quantity | Notes |
---|---|---|
Dried Red Chili Peppers | 50g | For heat and color; adjust based on spice preference |
Glutinous Rice Flour | 300g | Adds body and natural starch |
Water | As needed | Used for steaming and mixing |
Meju Powder or Soybean Paste | 200g | Source of fermentation; homemade or store-bought |
Salt | 60g | Preservative and flavor enhancer |
Brown Sugar or Honey | 50g | To balance out the spiciness |
Step-by-Step Guide to Making Gochujang Paste
Making gochujang is a bit like conducting a chemistry experiment with flavor. Follow these steps carefully:
- Prepare the Glutinous Rice: Steam 300g of glutinous rice flour until fully cooked and soft. Let it cool.
- Make Meju Paste: If using raw soybeans, boil and mash them into a paste. Alternatively, use store-bought meju powder mixed with water.
- Blend the Chili Mixture: Grind dried chilies into powder. Mix with salt, brown sugar, and cooled rice paste.
- Combine All Ingredients: Add meju paste and stir thoroughly until smooth and uniform.
- Pack into Fermentation Jar: Press mixture into a clean, sterilized jar. Cover with a cloth and secure with a rubber band.
- Ferment: Place in a sunny spot for 1–3 months. Stir weekly.
- Age and Enjoy: After fermentation, store in the fridge and let age further for deeper flavor.

Fermentation Tips for Perfect Gochujang
Fermentation isn’t just science — it’s also art. Here’s how to master it:
- Keep it clean: Sterilize jars and utensils before use to prevent mold.
- Temperature matters: Ideal range is between 20°C to 28°C (68°F to 82°F).
- Stir regularly: Once a week helps distribute flavors evenly.
- Don’t seal too tight: Allow airflow by loosely covering with cloth.
- Watch for mold: If white film appears, scrape it off. Dark mold means toss it out.

How to Use Gochujang in Your Cooking
Once you’ve got your batch ready, the fun begins! Here are some ideas:
- Gochujang Tacos: Swap traditional salsa for a spicy kick.
- Korean BBQ Marinade: Mix with soy sauce and garlic for tender grilled meats.
- Spicy Noodle Sauce: Stir into noodles with sesame oil and veggies.
- Dipping Sauce: Thin with vinegar and lime for dumplings or wings.
- Stew Enhancer: A spoonful adds depth to soups and stews.

Storing Your Homemade Gochujang Like a Pro
Your gochujang gets better with age — like a fine wine, but spicier. Here’s how to keep it fresh:
- Airtight container: Store in a glass jar with a tight lid.
- Refrigeration: Slows down fermentation and keeps it stable.
- Long-term aging: For stronger flavor, let it age in a dark pantry for up to a year.
- Label and date: So you know how old your batch is — trust us, you’ll forget!
Troubleshooting Common Gochujang Issues
So things didn’t go as planned? Here’s what might have gone wrong:
Issue | Cause | Solution |
---|---|---|
Mold growth | Contamination or poor airflow | Scrape off white mold; discard if black/green |
Too watery | Excess moisture | Strain or simmer gently to thicken |
Not enough spice | Low chili content | Add more chili powder next time |
Too salty | Over-salted | Dilute with rice flour or aged gradually |
No flavor development | Poor fermentation | Check temperature, stir more frequently |
