The practice of rice cooker: put egg white and egg yolk on two plates, add sugar to egg yolk, add milk after stirring, then stir, and then add flour to stir evenly. Add sugar to the egg white (add a little salt) and circle in one direction until the egg white becomes white foam. Pour the egg white into the egg yolk twice, stirring while pouring. Then put a layer of oil on the inner wall of the rice cooker, press the switch, jump up automatically, then pour the egg paste in, and press the switch. Don't turn it on after jumping up. Turn it on again in ten minutes. After one more jump, wait ten minutes. Then open the lid and poke it with chopsticks. If it is cooked, press the switch again. If you are not familiar with it, wait ten minutes and it will be ok.
