Pat the prawns dry and finely chop them by hand or pulse briefly in a food processor.

Transfer the chopped prawns to a bowl and add the green onions, garlic, ginger, soy sauce, sesame oil, white pepper, salt, and cornstarch. Mix until well combined.

Place a wonton wrapper on a clean surface.

Add about one teaspoon of filling to the center of each wrapper. Avoid overfilling, which can make sealing difficult.

Dip your finger into water and lightly moisten the wrapper edges.

Fold the wrapper diagonally to form a triangle and press firmly to seal. Bring the two corners together and press gently to create the traditional wonton shape.

Bring a large pot of water to a gentle boil.

Carefully add the wontons in batches and cook for about 4 to 5 minutes. They are ready when they float to the surface and the filling is fully cooked.

Use a slotted spoon to remove the cooked wontons from the water.

Allow excess water to drain before transferring them to serving bowls or plates.

Serve the wontons immediately with chili oil, soy sauce, sesame seeds, and chopped green onions.

Alternatively, place them in a bowl of hot broth to make a comforting wonton soup.
