Begin preparing the chicken stock by drizzling some oil in a pot on medium-high heat. Add in the chicken.
Stir-fry the chicken for 3-4 minutes.
Add the sliced ginger and spring onions to the chicken in the pot.
Stir fry for 1-2 minutes.
Add 1 litre of water to the pot.
Cover the pot with a lid. Simmer for 25 minutes over medium-high heat.
In a blender, add the pork, prawns, water chestnuts, light soy sauce, white pepper, sugar, salt, cornstarch, and sesame oil. Blitz for about 1 minute.
Take one wonton wrapper and add 1 tsp of filling. Wet one of the edges with water. Fold it close in a triangle shape. Tuck in the sides and crimp to seal. Make 10-20 wontons in the same way.
Cook the wontons in a pot of boiling water until the wontons begin to float.
Strain the stock and remove all the chicken, spring onions and ginger. The stock is now ready.
In the same pot, boil egg noodles with Chinese leaf. Season to taste and cook for about 3 minutes on medium heat.
In a serving bowl, place the egg noodles at the bottom, then the Chinese leaf. Top them with 2-3 wontons and pour over the broth.
Season with chopped scallions and enjoy it hot.
