Mul Naengmyeon (Korean Cold Buckwheat Noodles)

Korea's definitive summer cold noodle dish — thin, chewy buckwheat noodles in a cold, slightly sweet beef and radish broth. Served with cucumber, a hard-boiled egg, and pickled radish. The broth is everything: it must be cold enough that a thin layer of ice floats on top. The scissors come to the table to cut the long noodles — a Korean tradition.

Naengmyeon served cold enough to feel like the bowl is frozen — that is the standard. The broth should have a thin film of ice, the noodles should be rinsed under cold running water until they are completely cold, and the whole dish should shock you with temperature before the flavor registers.

Ingredients

Quick Beef Broth:

  • 400g beef brisket
  • 1.5 liters water
  • 3 tbsp soy sauce
  • 2 tbsp rice vinegar
  • 1 tsp sugar
  • 1 tsp salt
  • 1 tsp fish sauce (optional)
  • Optional: 200g Korean radish (mu), peeled

Noodles:

  • 200g naengmyeon noodles (buckwheat, dried or fresh — dried work well)

Toppings:

  • 1 hard-boiled egg, halved
  • 1/2 cucumber, julienned
  • Pickled radish (see note below)
  • 2 tsp Korean mustard (gyeoja) or hot mustard
  • 1 tsp rice vinegar (passed at table)

Method

Make broth: Place brisket (and radish if using) in a pot with 1.5 liters water. Bring to a boil, skim foam. Reduce to a simmer for 30 minutes. Remove brisket, slice thinly for topping. Strain broth. Season with soy sauce, rice vinegar, sugar, salt, fish sauce. Taste — it should be savory, slightly tangy, slightly sweet. Refrigerate until ice-cold. For service: add ice cubes or place bowl in freezer 10 minutes before serving.

Cook noodles: Boil naengmyeon noodles 3-4 minutes per package instructions. Drain. Rinse vigorously under cold running water, kneading the noodles to remove starch until water runs clear and noodles are cold. Portion into bowls.

Assemble: Pour cold broth over noodles. Top with cucumber, sliced brisket, egg half, pickled radish, Korean pear (if available).

At the table: pass scissors — Koreans cut naengmyeon noodles 2-3 times before eating (the noodles are very long). Pass rice vinegar and mustard to add at individual preference.

Pickled Radish (Quick)

Julienne 200g Korean radish (or daikon). Mix with 1 tbsp sugar, 1 tbsp rice vinegar, 1/2 tsp salt. Let sit 15-30 minutes. Drain lightly. Pink color comes from adding a small piece of beet or 1/4 tsp gochugaru.

Notes

  • The broth can be replaced with store-bought naengmyeon broth concentrate (available in Korean grocery stores) — dissolve 1 packet in cold water.
  • Buckwheat noodles are chewy-elastic — unlike ramen or soba. Don't overcook them. They should have significant bite.
  • Pyongyang-style (the original) is more delicate — lighter broth, plain garnish. Hamheung-style uses sweet potato starch noodles with gochujang sauce (bibim naengmyeon). This recipe is Pyongyang-style mul (cold broth) version.
