Instructions

1. 1

   Make the dough

   Stir the flour, instant yeast, sugar, and salt in a large bowl. Add the warm water and oil, then mix until a rough dough forms. Knead 8 to 10 minutes by hand, or 6 minutes in a mixer on low, until smooth and elastic. The dough should feel soft but not sticky; if it smears on your palm, knead in flour 1 tablespoon at a time.

   Water that feels hot to your hand is too hot for yeast. Aim for warm bath water, about 38 C, so the dough rises steadily without tasting yeasty.
2. 2

   Let it rise

   Shape the dough into a ball, put it in a lightly oiled bowl, cover, and let it rise in a warm place for 60 to 75 minutes, until nearly doubled. This rest is not decoration. It gives wang-mandu the soft, pillowy wrapper that separates it from thin-skinned mandu.

3. 3

   Dry the vegetables

   Toss the chopped napa cabbage with 1 teaspoon salt and let it sit 15 minutes. Squeeze it hard in a clean towel until no liquid drips. Press the tofu the same way and crumble it finely. A wet filling punishes you twice: it weakens the wrapper and makes the center taste flat.

4. 4

   Cook the noodles

   Boil the dangmyeon for 6 to 7 minutes, until fully tender, then rinse briefly and drain very well. Chop into 1 cm pieces. Long noodles pull the filling apart when you bite, so cut them short. They should carry seasoning, not behave like a second wrapper inside the dumpling.

5. 5

   Mix the filling

   In a large bowl, combine the pork, squeezed tofu, squeezed cabbage, chopped noodles, onion, carrot, scallions, garlic, ginger, soy sauce, sesame oil, oyster sauce if using, sugar, pepper, sesame seeds, egg white, and starch. Mix in one direction with your hand for 2 full minutes, until the pork turns sticky and binds the vegetables. That stickiness is structure, not fussiness.

6. 6

   Test the seasoning

   Pinch off 1 tablespoon of filling and cook it in a small pan or microwave until done. Taste it. It should be savory enough to stand up to the thick wrapper, with garlic and sesame present but not shouting. Add up to 1 teaspoon more soy sauce only if it tastes weak, then mix again. Do not taste raw pork.

7. 7

   Divide the dough

   Punch the risen dough down and divide it into 10 pieces, about 65g each. Roll each piece into a ball, cover with a towel, and rest 10 minutes. Rested dough rolls without fighting you; unrested dough shrinks back and makes thick, stubborn edges.

8. 8

   Roll the wrappers

   On a lightly floured surface, roll each dough ball into a 13 to 14 cm round, keeping the center slightly thicker than the edge. The center must carry the weight of the filling. Thin the edge so the pleats don't become a heavy knot at the top.

9. 9

   Fill and pleat

   Place about 85g filling in the center of each wrapper. Gather the edge upward, pleating as you go, and pinch firmly at the top to seal. Set each dumpling on a small square of oiled parchment or cabbage leaf. If the wrapper tears, you overfilled it or rolled the center too thin. Fix the next one. That is how hands learn.

10. 10

    Proof briefly

    Cover the shaped mandu and let them rest 15 to 20 minutes, until the wrapper looks a little puffed and relaxed. Do not let them double again. Too much proofing makes the surface wrinkled and the dough collapses when cooked.

11. 11

    Steam the mandu

    Bring water to a strong boil in a steamer pot. Arrange the mandu with at least 4 cm between them, because they expand. Cover and steam over medium-high heat for 18 to 20 minutes, until the wrapper is springy and the pork filling reaches 71 C in the center. Keep the lid closed. Lifting it early drops the temperature and toughens the wrapper.

    If cooking from frozen, do not thaw. Steam 24 to 26 minutes and check that the center reaches 71 C.
12. 12

    Rest and serve

    Turn off the heat and let the mandu sit covered for 3 minutes before opening the lid. This short rest helps the wrapper settle instead of shrinking. Stir together the dipping sauce ingredients and serve the mandu whole, with danmuji (yellow pickled radish) or a sharp kimchi beside them.

Chef Tips

• •Use pork with some fat. Lean pork makes a dry center, especially inside a large wrapper. If your pork is very lean, add 1 tablespoon neutral oil or finely minced pork belly to the filling.
• •The safe corner to cut is the steamer: a bamboo steamer, metal steamer basket, or wide pot fitted with a rack all work. The corner you cannot cut is removing water from the cabbage and tofu. Wet filling ruins wang-mandu quietly, from the inside.
• •Do not turn this into a noodle dumpling. Dangmyeon belongs here, but only 80g dried for the whole batch. More than that makes the filling loose and bland.
• •For kimchi wang-mandu, replace half the salted cabbage with 150g well-squeezed chopped baechu-kimchi. Taste before adding extra soy sauce, because kimchi brings its own salt and acidity.
• •Serve one or two per person as a meal with kimchi, danmuji, and a small bowl of broth. This is market food, but market food still deserves a proper table.

Advance Preparation

• •The dough can be mixed, kneaded, and refrigerated after the first 30 minutes of rise for up to 12 hours. Bring it to room temperature for 30 minutes before dividing.
• •The filling can be made 1 day ahead and refrigerated, tightly covered. Mix once more before filling because the noodles and vegetables settle.
• •Shaped, uncooked wang-mandu freeze well. Freeze them on a tray until firm, then bag them for up to 2 months. Steam straight from frozen, adding 6 to 8 minutes.
• •Cooked mandu can be refrigerated for 3 days. Reheat by steaming 8 to 10 minutes, not by microwaving until the wrapper hardens.
