Let’s prepare the ingredients for gyoza. Cut the cabbage leaf into strips. Chop them into 2~3mm (1/8″) pieces.
Slice the onion wedge but leave the root part attached. Chop the onion into 2~3mm (1/8″) pieces.
Chop the garlic chive stems first. Cut the leaf parts in half and chop them into fine pieces. Grate the garlic clove and ginger root.
Let’s make the gyoza filling. Knead the ground pork in a bowl until a bit gooey. Add the soy sauce, sugar, pepper, sake, sesame oil, potato starch, grated garlic, grated ginger and oyster sauce to the ground pork.
Knead the mixture thoroughly. The thickness shown in the video is ideal to give the filing a juicy texture when cooked.
Add the chopped cabbage, onion and garlic chives to the mixture. Lightly stir until evenly mixed.
Cover the bowl with a plastic wrap. Keep the mixture in a fridge for 30 minutes to make the pork and vegetables blend well together.
Let’s wrap the filling with gyoza wrappers. Sprinkle some flour on a baking sheet to keep the gyoza from sticking. This will also give the gyoza an extra crispiness.
Scoop the filling and spread it onto the wrapper.
Wet the edges of the wrapper.
Fold the wrapper in half and begin forming pleats only on one side. This is one example of how to wrap the fillings and you can arrange it as you like.
Place Gyozas on the baking sheet.
Let’s make gyoza sauce. Put the black vinegar and soy sauce in a bowl. Stir lightly.
Let’s cook the gyoza. Heat the sesame oil in a frying pan over medium heat. Arrange the half of the gyoza in the pan. Make a little space between each Gyoza so that they don’t stick together.
Pour over boiling water until they are half submerged.
Put a lid on and cook over medium-high heat for about 5 to 6 minutes.
When the water has evaporated and gyoza start to sizzle, remove the lid. Add some more sesame oil to the gaps of gyoza and replace the lid. Cook for 1 to 2 more minutes.
When the bottom becomes golden brown, turn off the burner and remove the gyoza with a spatula.
Place the gyoza onto a plate with the bottom side up. You can add rayu (hot chili oil) or sesame oil to the gyoza sauce to your taste.
The uncooked filling will easily go bad even if stored in the fridge so cook it as soon as possible.
This recipe can be a great side dish for ramen noodles.
