Put the shrimp into a bowl and add ¼ teaspoon of salt, 1 teaspoon of cooking wine, and 2 dashes of black pepper. Mix and marinate for 10 minutes before using.
Mix cornstarch with water firstly and then whisk the eggs in a bowl, and add ¼ teaspoon of salt, 1 teaspoon of light soy sauce, and a mixture of cornstarch and water (stirred together in a ratio of 1:2). Mix well and set aside for later use.
Heat cooking oil (highly recommend using non-stick pan) and fry the shrimp until pink. It should be very quick. When cooking your shrimp, be careful not to overcook them. Fry them just until they curl and turn slightly pink, only half cooked please.
Pour in egg mixture and let it stay for 3-5 seconds until the mixture starts to bubble up.
Slow down the heat and give a gentle stir to make sure that there is no egg sticky to the bottom of the pan. When you see the egg mixture start to solidify at the bottom of the pan, push it to one side to allow the new egg mixture to flow into the empty space. Repeat this action several times until the eggs are cooked to a smooth and custardy consistency. Sprinkle chopped scallions on top of the eggs and serve.
