200 g (7 oz) firm tofu, crumbled and squeezed dry in a towel
150 g (1 cup) well-fermented kimchi, chopped and squeezed dry
50 g (2 oz) dangmyeon (sweet potato glass noodles), boiled 6 minutes, rinsed and chopped
100 g (1 cup) mung bean sprouts, blanched 1 minute, squeezed and chopped
3 scallions, finely chopped
3 garlic cloves, minced
1 tsp grated ginger
1 tbsp soy sauce
1 tbsp sesame oil
1 tsp sugar
1/2 tsp salt
1/4 tsp black pepper
1 egg
36 round mandu or dumpling wrappers
For the dip: 3 tbsp soy sauce, 1 tbsp rice vinegar, 1 tsp gochugaru, 1 tsp sesame seeds
How to make it
Prep the vegetables (20 min): Squeeze the tofu, kimchi and sprouts as dry as you can; wet filling makes soggy mandu.
Mix the filling (5 min): Combine pork, tofu, kimchi, noodles, sprouts, scallions, garlic, ginger, soy, sesame oil, sugar, salt, pepper and egg. Knead by hand 1 minute.
Wrap (25 min): Put a heaping tablespoon in each wrapper, wet the edge, fold into a half-moon and press out the air. For the round Gaeseong shape, bring the two corners together and pinch.
Steam (10 min): Steam on oiled parchment over boiling water for 10 minutes, until the wrappers turn translucent.
Or pan-fry (8 min): Fry in a tablespoon of oil until golden on one side, add 60 ml (1/4 cup) water, cover 4 minutes, uncover and crisp 1 minute.
Or make manduguk (10 min): Simmer 1.5 liters beef or anchovy stock, season with soy, drop in 12 mandu and simmer 6 minutes until they float, then swirl in a beaten egg and top with scallions and seaweed.
Serve with the dip.
Tips
Mandu freeze well; most Korean families make a big batch before the Lunar New Year.
