One by one, lightly wet the edges of the wonton wrappers with your finger, add 1 heaped teaspoon of filling to the middle of each, and pinch together to seal (don’t stress if they tear every now and again), placing them in a large oiled nonstick frying pan as you go.,

Put the pan over a high heat, then pour over 150ml of water and cover. Let it steam until the water has completely evaporated, then uncover and allow to fry, removing as soon as the bottoms are golden and crisp.,

Meanwhile, peel the remaining ginger, finely grate with the chilli, and place in a small dipping bowl. Trim and finely shred the spring onions, toast the sesame seeds, then serve with soy, mustard and lime wedges.
