[Korean Recipe] Authentic Korean Pepper Pickles in Fish Sauce (Gochu-jeotguk-jangajji)

Traditional Korean Pepper Pickles

Gochu-jeotguk-jangajji is a traditional Korean fermented side dish (mitbanchan) that captures the refreshing crunch of summer peppers. Unlike the vinegar-based pickles common in the West, these use a savory brine of fish sauce and dried anchovies to create a deep, umami flavor profile. This recipe focuses on the 'asagi gochu' variety—a mild, juicy, and incredibly crispy Korean pepper—though it can be adapted for those who prefer more heat.

• Easy Fermentation: A simple process that creates a long-lasting side dish for your refrigerator.
• Crunchy & Juicy: Using traditional techniques ensures the peppers stay firm and burst with savory juice in every bite.
• Zero-Waste Brine: The leftover pickling liquid is a goldmine of flavor that can be reused in soups, stews, or as a soy sauce substitute.

Ingredients

Servings: Makes one 1-gallon jar

• 2 lbs Korean green chili peppers (non-spicy 'asagi gochu' is best), washed and drained
• 8 cups water
• 1 1/4 cups fish sauce
• 1/2 cup kosher salt
• 12 large dried anchovies (approx. 2.5 inches long), heads and guts removed

Step-by-Step Instructions

1. Prepare the Peppers: Trim the stems of the peppers, leaving about 1/2 inch at the top. Using a toothpick or a metal chopstick, poke a small hole in each pepper just below the stem. This allows the brine to seep inside. Place all peppers into a clean one-gallon glass jar.
2. Simmer the Brine: In a large pot, combine the water, fish sauce, salt, and cleaned dried anchovies. Cover and bring to a boil over medium-high heat. Let it simmer for 30 minutes.
3. Cool and Submerge: Remove the pot from heat and discard the anchovies. Allow the brine to cool down completely. Once cool, pour it over the peppers in the jar. Place a fermentation weight or a clean rock on top to keep the peppers fully submerged. Cover and refrigerate for 24 hours.
4. The Second Boil: After 24 hours, pour only the brine back into a pot. Bring it to a vigorous boil for 20 minutes over medium-high heat. This step stabilizes the fermentation. Remove from heat and let the brine cool thoroughly once again.
5. Final Fermentation: Pour the cooled brine back into the jar with the peppers. Replace the weights and cover tightly. Refrigerate for at least one week before serving.

Tips & Substitutions

• Pepper Varieties: If Korean peppers aren't available, Anaheim peppers are a great mild substitute. For those who love spice, you can mix in some Thai chilies or serranos.
• Heat Control: The 'asagi' variety is known for being sweet and mild. If you want a bit of a kick without overwhelming heat, use a mix of 80% mild and 20% spicy peppers.
• Proper Storage: Always keep the peppers submerged in the brine while they are in the fridge to prevent spoilage and maintain their crisp texture.
• Serving Suggestion: These pickles are best enjoyed with a simple bowl of warm steamed rice. The salty-savory juice acts as a perfect seasoning for the grain.
