Radish Kimchi
Ingredients
- 3 pounds Korean radish (mu) – peeled and cut into 1-inch cubes (~1.5 large korean radishes)
- 2 1/2 tbsp coarse sea salt
- 1 tbsp sugar (13g)
- 1/2 cup Korean red pepper flakes (gochugaru)
- 3 tbsp fish sauce
- 2 tbsp salted shrimp (saeujeot) – finely chopped
- 2 tbsp garlic – minced
- 2 tsp ginger – minced
- 1/4 cup water
- 4 scallions – cut into 1-inch pieces

Instructions
- 1.
Wash a 2-quart glass jar and lid with hot, soapy water and let air-dry.
- 2.
Place the cubed Korean radish in a large bowl. Sprinkle with coarse sea salt and sugar, toss well, and let stand 45 minutes, tossing once or twice, until the radish releases liquid and softens slightly.
- 3.
Drain the radish in a colander, reserving 2–3 tablespoons of the brine if possible. Do not rinse. Return the radish to the bowl.
- 4.
In a separate bowl, mix the gochugaru, fish sauce, salted shrimp, minced garlic, minced ginger, and the water (or reserved brine) to form a thick paste.
- 5.
Add the paste and the scallions to the drained radish. Toss with gloved hands until every piece is evenly coated and the mixture is glossy and slightly juicy.
- 6.
Pack the kimchi into the clean jar, pressing down firmly to remove air pockets and to bring the brine up to cover the radish. Leave 1–2 inches of headspace.
- 7.
Wipe the rim, seal loosely (or use an airlock lid), and leave at cool room temperature (65–72°F) for 24–48 hours. Burp once daily if using a standard lid. Ferment until you see active bubbles and the brine rises to cover, and the taste is lightly tangy.
- 8.
Tighten the lid and refrigerate at least 12 hours before serving to settle flavors. The kimchi will continue to mature over 1–2 weeks; keep the radish submerged in brine and use clean utensils each time.
Radish Kimchi, known as kkakdugi, is a crunchy, juicy kimchi made from large white Korean radish cut into cubes. The flavor is bright and peppery with a clean heat from gochugaru, rounded by garlic and ginger and deeply savory from fermented seafood. Its brine is appetizing and lightly effervescent, making it a refreshing counterpoint to rich soups, stews, and grilled meats.
Rooted in the broader kimchi tradition, kkakdugi likely developed alongside other radish-based ferments as a way to preserve late-season crops. It is especially beloved with hearty broth dishes like seolleongtang and galbitang, where its crisp texture and tang cut through the richness. Over time it has become a staple banchan across Korea, appearing at home tables and restaurants year-round.
