We cannot get enough of these dumplings. The filling is super-savory, and I'm just gonna leave the word CRAVE here rather than subjecting y0u some horrible adjective Frankenform of that term. It's definitely a project to make your own dough and roll out each little circle before filling and cooking it, but sometimes you want a kitchen project, right? This recommend Dough is lightly adapted from the wonderful Molly Yeh's family recipe on Food52.
For the dough:
In a medium mixing bowl, stir together the flour and salt. Pour in the boiling water a little at a time and mix with a spoon until incorporated. Then pour in the cold water a little at a time, continuing to mix until you have a very wet, sticky dough.
Sprinkle plenty of flour onto a work surface and your hands. Scrape dough from bowl onto work surface and knead, adding more flour as necessary to prevent sticking, until dough is smooth. (See video above for visual cues here and throughout the recipe.) Place dough in a clean bowl, cover with a clean kitchen towel, and let rest while you make the filling.
For the filling:
Place the pork in a medium mixing bowl. Remove white stems from cabbage leaves and finely shred the green leafy parts with a knife. Add shreds to mixing bowl. Add egg to one side of bowl and lightly beat with a fork. Add ginger, garlic, soy sauce, sesame oil, salt and scallions to bowl. Use your hands to combine the mixture thoroughly without compressing it.
To fill and shape the dumplings:
Pinch off dough by the tablespoon (approximately -- don't stress). Roll into a ball between your palms and place onto a floured work surface. Roll out with a floured rolling pin into a 3- to 4-inch circle. Place a tablespoon of filling into the center and fold dough into a semicircle around filling. Use your fingers to press the edges of the dough together and then to crimp the edges. (Again, see video. It's not hard at all, promise, but a little imagery goes a long way. ) This process takes a WHILE, and it's fun to have help.
To cook the dumplings:
Bring a large pot of well salted water to a boil. Add dumplings in batches of about 8 and boil on medium-high heat for four minutes. Meanwhile, set a large frying pan with two tablespoons of safflower oil over medium heat. After boiling, carefully shake or blot excess water from dumplings and add dumplings in batches to frying pan. Cook for a few minutes until undersides are browned, being careful for splatters. Blot excess oil from dumplings before serving with dipping sauce.
To make the dipping sauce:
Stir together tamari, rice vinegar and hot chili sesame oil in a small bowl.
