📝 About This Recipe

Dongchimi is a refreshing, crisp, and naturally carbonated water kimchi that is a cornerstone of Korean winter tradition. Unlike its spicy red counterparts, this 'white' kimchi relies on a clear, salty brine infused with the essence of pear, ginger, and garlic to create a sophisticated flavor profile that is both savory and sweet. It serves as a perfect palate cleanser, a cooling digestive aid, or the soul-soothing base for a bowl of cold buckwheat noodles.

🥗 Ingredients

The Radish Foundation

  • 2 kg Korean Radish (Mu) (small to medium sized, firm and heavy)
  • 1/2 cup Coarse Sea Salt (Korean solar salt is preferred for fermentation)
  • 2 tablespoons Sugar (to help draw out moisture and add a hint of sweetness)

Aromatic Brine Base

  • 4 liters Water (filtered or boiled and cooled)
  • 1 large Korean Pear (peeled and poked with holes)
  • 1 medium Onion (peeled and halved)
  • 10 cloves Garlic (thinly sliced)
  • 1 piece Ginger (2-inch knob, thinly sliced)

Vegetable Accents

  • 10 stalks Scallions (tied into small bundles)
  • 2-3 pieces Red Chili Peppers (dried or fresh, for a hint of color and heat)
  • 2-3 pieces Green Chili Peppers (fermented peppers are traditional if available)
  • 100 grams Korean Mustard Greens (Gat) (optional, for a peppery kick)

👨‍🍳 Instructions

  1. 1

    Scrub the radishes thoroughly with a brush under cold water. Do not peel them, as the skin keeps the radish crunchy during the long fermentation process.

  2. 2

    Place the whole radishes in a large bowl. Rub them generously with 1/4 cup of the sea salt and the sugar. Let them sit at room temperature for 12-24 hours until the radishes soften slightly and release their juices.

  3. 3

    While the radishes brine, prepare the aromatics. Place the sliced garlic and ginger into a fine mesh tea ball or a small cheesecloth pouch to keep the brine clear.

  4. 4

    In a separate large container, dissolve the remaining salt into the 4 liters of filtered water. Stir until the water is crystal clear.

  5. 5

    Wash the scallions and mustard greens. Take 2-3 stalks of scallions and tie them into a neat knot; repeat until all are bundled. This prevents them from becoming a tangled mess in the jar.

  6. 6

    Take the Korean pear and poke it several times with a skewer or fork. This allows the sweet juices to infuse into the brine without the fruit disintegrating.

  7. 7

    In a large, sterilized glass jar or fermentation crock, place the brined radishes at the bottom, including any liquid they released during the salting process.

  8. 8

    Layer in the pear, onion halves, bundled scallions, mustard greens, and the chili peppers.

  9. 9

    Tuck the spice pouch (garlic/ginger) deep into the center of the vegetables.

  10. 10

    Pour the prepared salt water over the vegetables until everything is completely submerged. If the vegetables float, use a fermentation weight or a clean plate to keep them down.

  11. 11

    Seal the jar and let it sit at room temperature for 2 to 3 days. You will know it is ready when tiny bubbles appear and the brine tastes pleasantly tart and tangy.

  12. 12

    Once fermented, move the jar to the refrigerator. It is best served chilled after another 3-4 days of cold aging, which develops the 'sparkling' mouthfeel.

💡 Chef's Tips

For the best crunch, choose small, dense 'altari' or young Korean radishes if available. Ensure the pear is fully submerged; if it stays above the water line, it may brown or develop mold. If you prefer a sweeter brine, you can add a few slices of apple along with the pear. Avoid using table salt; the additives can make the brine cloudy and the vegetables mushy. If the brine is too salty after fermentation, you can dilute it with a little bit of cold water just before serving.

🍽️ Serving Suggestions

Serve the radish sliced into bite-sized rounds or batons, submerged in a bowl of the cold brine. Use the chilled brine as a base for 'Dongchimi Guksu' (cold noodles) by adding somyeon or buckwheat noodles. Pair it with heavy, fatty dishes like Galbi (short ribs) or Bulgogi to act as a refreshing palate cleanser. Serve alongside Korean sweet potato (Goguma) as a traditional winter snack; the acidity perfectly balances the starchy sweetness. Garnish with a few pomegranate seeds or thin slices of red chili for a beautiful festive presentation.
