Dry the shrimps with kitchen paper and then add pinch of salt, pepper and sesame oil. Set aside for 10-15 minutes.
And then well beaten all the eggs in a large bowl. Stir in warm water, salt, sugar and mix well.
Heat around 1 tablespoon of butter in pan (highly recommend using non-stick pan) and fry the shrimp until pink. It should be very quick. Mix shrimp with egg liquid.
Keep the butter and add another 1 tablespoon of butter in. Pour in egg mixture and let it stay for 6-10 seconds until the mixture starts to bubble up. Then remove from the heat and give a gentle stir to make sure that there is no egg sticky to the bottom of the pan. Keep stirring for around 10 to 15 seconds. Transfer out immediately. Sprinkle some fresh chopped scallion and ground pepper before serving.
