Pan-fried, then steamed, then fried again in the same pan: soft tops, crackling golden bottoms and an optional lacy starch skirt that joins them into one crisp sheet.
For the filling: 300 g (2/3 lb) ground pork, 25% fat
200 g (2 cups) napa cabbage, finely chopped
1 tsp salt (for the cabbage)
2 scallions, minced
1 tbsp grated ginger
1 tbsp light soy sauce
1 tsp Shaoxing wine
1/2 tsp sugar
1/4 tsp white pepper
1 tsp sesame oil
30 round dumpling (gyoza/jiaozi) wrappers
To fry: 2 tbsp neutral oil, plus 1 tsp for the skirt
For the skirt (optional): 1 tbsp flour or cornstarch whisked into 150 ml (2/3 cup) water
To serve: soy sauce, black vinegar and chili oil
How to make it
Salt the cabbage (15 min): Toss the cabbage with the salt and leave 15 minutes, then squeeze out as much water as you can in a towel.
Make the filling (5 min): Stir the pork with the cabbage, scallions, ginger, soy, wine, sugar, pepper and sesame oil in one direction until sticky.
Wrap (20 min): Put a tablespoon of filling in each wrapper, wet the edge, fold in half and pleat the front edge into a crescent, or simply pinch shut. Set flat side down.
Fry (3 min): Heat 2 tbsp oil in a 25 to 30 cm nonstick skillet with a lid over medium-high. Arrange the dumplings flat side down in a tight spiral. Fry 2 to 3 minutes until the bottoms are lightly golden.
Steam (7 min): Pour in the skirt mixture (or 150 ml plain water), cover at once and cook over medium for 6 to 7 minutes until the water is nearly gone.
Crisp (3 min): Uncover, drizzle the extra teaspoon of oil around the edge and keep frying until the bottoms and the skirt turn deep golden and crisp, 2 to 3 minutes. Loosen with a spatula.
Flip and serve: Put a plate over the pan and turn it over so the crisp side is up. Serve with soy, vinegar and chili oil.
Tips
Squeezing the cabbage is the difference between juicy and soggy.
A nonstick pan makes the skirt release in one sheet.
