Memil-soba.

Most memil-soba recipes are the dipping kind — cold noodles on a bamboo mat, tsuyu in a small bowl on the side. Dallae's version is the slurp kind (냉모밀): the noodles sit IN the broth, and you eat it like guksu. Faster to serve, easier to share, and the freezer trick keeps it colder than any dipping bowl.

The whole thing rests on one number: 6 cups water to 1 cup tsuyu concentrate. Halve to 3·1 if you'd rather do dipping-style (자루소바). Everything else — the katsuobushi steep, the grated-radish ball, the freezer-slushed broth — is technique on top of the ratio.

Ingredients

The broth (2·5 servings — Dallae's original ~4 portions)

• 6 mug cups water (~1.4L)
• 1 mug cup 메밀소바장국 (Korean or Japanese tsuyu concentrate)
• 1 handful (1줌) katsuobushi (가스오부시, bonito flakes)

The oroshi (grated-radish ball)

• ⅓ Korean radish (무), grated on a fine grater
• Wasabi to taste, mixed in — optional

The noodles + garnish

• 400g buckwheat noodles (메밀면) — get one with high buckwheat content
• 4–5 stalks 쪽파 (spring onion / chives), thin-sliced
• 1 sheet roasted nori (김), cut into thin strips
• Wasabi to taste, on the side

Method

1. Mix the base. In a pot, combine 6 cups water and 1 cup tsuyu concentrate (per mug cup). If you want dipping-style instead, use 3 water : 1 tsuyu.
2. Boost with katsuobushi. Add a handful of bonito flakes. Bring to a boil — even though the tsuyu is already flavored, the fresh katsuobushi deepens it. Boil until strong, then fish the flakes out.
3. Boil once more. Return the strained broth to high heat. The moment it hits a rolling boil again, kill the heat.
4. Freezer-slush the broth. Portion into ziplock bags (one per serving). Lay flat in the freezer for 30–40 minutes — you want a soft slush, not a solid block.
5. Make the oroshi. Grate Korean radish on the finest grater you have. Squeeze the juice out gently — don't wring it dry. Shape into little balls.
6. Plate the garnish. Oroshi and spring onion go on separate small dishes. Have the nori strips and wasabi within reach.
7. Cook the noodles. Boil 400g memil-myeon for 5 minutes. When it foams up, splash in cold water to calm it — Dallae's trick to keep the noodles from mushing at the surface. Stir occasionally so they don't stick.
8. Ice-rinse. Drain into a colander, rinse very hard under cold running water, rubbing the noodles between your hands until the surface is slick and squeaks. Drain very well.
9. Assemble. Nest noodles in a wide bowl. Pull the slushy broth from the freezer, mash the bag with your palms, and pour over the noodles. Drop the oroshi ball on top, shower with spring onion and nori strips. Wasabi on the side.

Tip · why 6·1 (and when 3·1)

6 cups water to 1 cup tsuyu is Dallae's slurp-style dilution — the broth reads as light, drinkable, sour-savory. If you want the traditional dipping-style (자루소바 / 판메밀) where you dip a chopstick-load into a small bowl of concentrated broth, halve the water: 3 cups water to 1 cup tsuyu. Same tsuyu, two different dishes.

Tip · the freezer-slush move

Bagging the broth and slushing it in the freezer for 30–40 minutes is what makes this the coldest bowl on the summer table. You want it soft-slushy — you can still pour it — not a solid frozen brick. Room-temp broth over cold noodles equals lukewarm noodles, which is nobody's dream. Skip this at your peril.

Tip · katsuobushi even with bottled tsuyu

Bottled tsuyu is already dashi-based and works fine on its own — but Dallae swears by re-boiling the diluted broth with a handful of fresh katsuobushi (가스오부시). One handful, two-minute steep. The bonito is stronger fresh than it is in the bottle.

Tip · oroshi is not garnish

The little grated-radish ball (오로시) isn't decoration. As you eat, break it apart into the broth — the raw radish sharpens the tsuyu and adds a cool, peppery snap. Mix wasabi into it if you want more heat.
