Combine the ground pork, finely chopped cabbage, finely chopped onion, minced garlic, and grated ginger in a bowl. Mix until cohesive. The filling should hold its shape when pressed but release no standing liquid — if wet, the wrapper base will fail to crisp.

Place a wrapper flat. Spoon a portion of filling into the centre, leaving a clear border. Fold and pleat the edge to seal. Repeat for all gyoza. Wrappers must be sealed with no air pockets — any gap will burst during steaming.

This is where the dish lives or dies. Arrange the gyoza in concentric circles in a cast-iron pan, leaving a 2 cm space in the centre. Heat 1 tbsp neutral oil over medium-high heat. Add the gyoza in their circular formation. Fry undisturbed until the bases are golden and audibly sizzling — the sound will quiet slightly as the raw dough sets and begins to colour.

Whisk the flour into the water until lump-free to make the hane-gyoza slurry. Pour the slurry around the edges of the circular formation — not into the centre space. Cover immediately with a lid. Steam until the slurry has evaporated and the wrapper tops appear translucent and cooked through.

Remove the lid. Allow residual moisture to evaporate fully. For Utsunomiya double-fry: add a second measure of oil around the edges and fry again until the bottom crust is deeply crisp and the connected wing formation is rigid and lace-like. The crust should release cleanly from the pan when tested at one edge with a spatula.

Place a flat plate over the pan. Invert in one confident motion so the entire circular formation lands crust-side up, wing intact. Place the raw bean sprout mound in the centre space immediately. Serve without delay — the crust softens within minutes.
