Chop the cabbage, shrimp, 4 scallions (keep the 5th for presentation) and pour everything into a bowl.

Add to the bowl, the chilli, salt, soy sauce, 1 teaspoon sesame oil, chopped garlic, ginger and toss well.

Place the filling in the centre without touching the edges.
Moisten with water the edges for better adhesion.
Fold the dough to form the gyoza (example of folding on Cooknvibe's IGTV)

In a frying pan, heat 2 tbs of sesame oil and place the gyozas over medium heat until the bottom is golden (about 2 minutes).

Add enough water to cover the bottom of the pan (about 3mm), cover and cook until the water evaporates.

Place the gyozas on a plate. Add sesame seeds and the green part of the 5th scallion.

You can accompany the gyozas with a sauce consisting of 1/3 soy sauce and 2/3 rice vinegar or punzu sauce.
