Toss shredded cabbage with salt. Leave 20 minutes. Squeeze out as much liquid as possible.

Combine pork, drained cabbage, spring onions, ginger, garlic, soy, Shaoxing, sesame oil, white pepper and cornflour. Mix one direction for 2 minutes.

Place 1.5 tbsp filling in the centre of a wonton wrapper. Bring the four corners up to meet at the top, pinch to seal, leaving the corners pinched up like a flower.

Repeat. Place on a tray dusted with cornflour.

Bring water to the boil under a steamer. Lay dim sims on a piece of baking paper inside the steamer (don't let them touch each other). Steam 12 minutes.

Optional: heat 2 tbsp oil in a non-stick pan, place dim sims in flat-side-down, fry 90 seconds until bottoms are golden.

Serve with soy sauce, black vinegar, chilli oil.
