Tips:1. When cooking eggs, put the eggs in a pot under cold water, soak them in cold water for a few minutes, then turn on medium heat until the water boils. After the water has boiled, boil for about 8 minutes, remove it, and let it cool in cold water. Egg yolks boiled to this level are dry and easy to pass through the screen.
2. The dough after refrigeration is more drier and harder, when you press it with your thumb
