For the wontons: 300 g (10 oz) raw shrimp, peeled and roughly chopped, 100 g (3 1/2 oz) fatty ground pork, 1 tsp salt, 1/2 tsp sugar, 1 tsp sesame oil, white pepper, 1 tsp cornstarch, 1 egg white; 30 thin square wonton wrappers
For the broth: 1.5 liters (6 cups) chicken or pork broth, 20 g dried flounder or 2 tbsp dried shrimp, 1 tbsp dried shrimp roe (optional), 1 tbsp light soy, salt and white pepper
4 portions fresh thin Hong Kong egg noodles (about 300 g / 10 oz)
To serve: 4 stems yellow chives or scallions cut short, gai lan or choy sum blanched, oyster sauce
How to make it
Filling (10 min): Mix the shrimp, pork, salt, sugar, sesame oil, pepper, cornstarch and egg white, then stir hard in one direction 2 minutes until sticky. Chill 20 minutes.
Wrap (20 min): Put 1 tsp filling in the middle of a wrapper, wet the edges, fold into a triangle, then bring the two corners together and press. Keep them under a towel.
Broth (20 min): Toast the dried flounder in a dry pan until fragrant and golden, then simmer in the broth 20 minutes and strain. Season with soy, salt and pepper.
Cook (5 min): Boil the wontons in a big pot until they float plus 1 minute. In another pot, boil the noodles 20 to 30 seconds only; rinse quickly under cold water to stop them, then dip back in the hot water to warm.
Build: Put the wontons in the bowl first, then the noodles on top, pour over boiling broth and add yellow chives. Greens with oyster sauce on the side.
Tips
The cold rinse and quick reheat is what keeps the noodles al dente.
Freeze extra wontons on a tray, then bag them; cook from frozen, 2 minutes longer.
