Make the filling
Add the minced prawns, chives, chicken powder, salt, garlic, white pepper, light soy sauce, oyster sauce, sesame oil and cornflour to a bowl.
Mix everything together until well combined and slightly sticky and paste-like.
Fold the wontons
Place a wonton wrapper in the palm of your hand and add around 1 tsp of filling to the centre.
Dab a little water around the edges, then bring the edges together and pinch tightly to create a little pouch or fishtail shape.
Repeat until you've used up all the filling.
Make the spicy chilli sauce
Add the garlic, sugar, chicken powder, chilli powder and sesame seeds to a heatproof bowl.
Heat the neutral oil until hot, then carefully pour it over the aromatics.
Add the chilli oil or chilli crisp, light soy sauce and black vinegar. Mix well, taste and adjust to your liking - more vinegar for tang, chilli oil for heat or sugar for sweetness.
Cook the wontons
Bring a large pot of water to a boil.
Carefully add the wontons and cook for around 5 minutes, or until cooked through. If using frozen wontons, you may need an extra minute or two.
Remove them with a slotted spoon and transfer them straight into the bowl with the chilli sauce.
Toss & serve
Give the wontons a good toss until they're completely coated in that spicy, garlicky sauce.
Transfer to a serving plate and garnish with more chopped chives or spring onions.
