A small round white porcelain bowl holds pale pleated steamed dumplings filled with brown shiitake mushrooms, pale napa cabbage, ground pork and minced ginger, with wooden chopsticks resting beside the bowl.
Boiled, steamed and pan-fried dumplings, wontons and other filled dough foods.
Zheng jiao are steamed dumplings; jiaozi can be boiled, steamed or pan-fried, with a wheat wrapper and fillings such as pork, shrimp, fish and vegetables. Cantonese dumplings served as dim sum are usually steamed and have thinner wrappers. This method combines 2 recipes: a hot-water dough recipe and a family recipe for pork, shiitake and napa cabbage filling, which uses store-bought wrappers. The steamed form has no established date; dumplings from the Astana cemetery at Turpan date to the Six Dynasties through the Tang, but these dates concern dumplings in general, not specifically steamed ones.
What
Zheng jiao are thin-wrapped dumplings with a meat or vegetable filling, cooked by steaming. Jiaozi can be boiled, steamed or pan-fried, with a wheat wrapper and fillings such as pork, shrimp, fish and vegetables; steaming is one of 6 cooking methods.1,2
When
The steaming method has no established date; dumplings from the Astana cemetery at Turpan include some dated to the Six Dynasties (220 to 589) and others to the Tang, but these dates concern dumplings in general, not specifically steamed ones.3
Where
Jiaozi are especially associated with northern China. Cantonese dumplings served as dim sum are usually steamed and have thinner wrappers.1,2
How
This method combines 2 recipes: make a hot-water dough with 3 cups of flour, 1 cup of boiling water and 1/4 cup of room-temperature water, knead for 10 to 15 minutes and rest for 30 to 60 minutes, then roll into rounds, fill and pleat. Line the steamer with cabbage leaves or parchment, set the dumplings about 2.5 cm apart, and steam over medium heat for 8 to 10 minutes.4,5,6
Why
Dumplings are a New Year food whose shape recalls gold ingots and symbolizes wealth.3,6
Impact and influence
Steamed dumplings are made at home and are also a kind of Cantonese dim sum dumpling.2,4,6
Legend has it that at the end of the Eastern Han the physician Zhang Zhongjing wrapped mutton and warming herbs in dough shaped like ears and gave them with soup to people whose ears were frostbitten; the custom of eating dumplings at the New Year is said to follow from this.
Told in: A folk tale. Chinese and English Wikipedia both present it as folklore with no source from the time, and it concerns jiaozi in general, not steamed ones.
This is a simplified home version, not the traditional restaurant method.
This is the steamed dumpling I make at home, with the dough and the filling taken from two different recipes. The dough follows a signed hot-water dough recipe, including its amounts and its kneading and resting times. The filling follows a family recipe for pork, shiitake and napa cabbage, published through a cooking blog, which uses store-bought round wrappers and was written for about 72 small dumplings, so I roll my own wrappers from the hot-water dough, and how much filling goes in each follows the dough recipe. The steaming time, 8 to 10 minutes, agrees across the two recipes and a signed guide to cooking dumplings. The conversions from cups and pounds to grams and milliliters are my estimates.
Ingredients
All-purpose flour, for the dough 3 cups, about 375 g (my estimate of the conversion)
Boiling water, for the dough 1 cup, about 240 ml
Room-temperature water, for the dough 1/4 cup, about 60 ml
Vegetable oil, for the dough 1 teaspoon
Dried shiitake mushrooms 10, soaked in 2 cups (about 480 ml) of hot water, keeping 1/2 cup of the soaking liquid
Napa cabbage about 450 g, chopped and tossed with 1 teaspoon of salt
Vegetable oil, for the mushrooms 1 tablespoon
Ground pork about 450 g
Shaoxing wine 1/4 cup, about 60 ml
Soy sauce 1 1/2 tablespoons
Minced ginger 1 tablespoon
Sugar 2 teaspoons
Toasted sesame oil 2 teaspoons
White pepper 1/2 teaspoon
Steps
Soak the dried shiitake in hot water for 2 hours or overnight, lift them out and chop the caps, and keep 1/2 cup of the soaking liquid.
Make the dough: stir the boiling water into the flour, add the room-temperature water and the oil, and knead to a dough for 10 to 15 minutes. Cover it and rest it for 30 to 60 minutes. The amounts and times follow the dough recipe.
Chop the cabbage, toss it with the salt, leave it for up to 30 minutes and squeeze it dry.
Heat 1 tablespoon of oil in a pan, fry the chopped mushrooms for about 5 minutes and let them cool.
Put the ground pork in a bowl with the wine, soy sauce, ginger, sugar, sesame oil, white pepper and the 1/2 cup of mushroom liquid, and stir for 10 to 15 minutes, until pasty. Then mix in the cabbage and mushrooms.
Divide the dough into small pieces and roll each into a round 10 to 11 cm across.
Put about 2 tablespoons of filling (the amount in the dough recipe) in each wrapper, fold it over, and pleat and seal the edge.
Line the steamer with cabbage leaves or parchment, set the dumplings about 2.5 cm apart and steam them over medium heat for 8 to 10 minutes.
The pork must be cooked through. I cut one open, and I serve them just when the filling has no pink and the juices run clear.
Tips
The filling recipe says to cook the dumplings at once or freeze them at once; I also steam them as soon as they are filled.
If you use store-bought wrappers, follow that recipe and put a scant tablespoon in each. My wrappers are rolled by hand and larger, so I put in a little more.
