Crack the eggs into a bowl.
Use some chopsticks to beat the eggs into a smooth liquid. (Be sure to mix up the eggs well otherwise the eggs will steam unevenly.)
Boil the water and then let it cool. After it has cooled down a bit, pour it into the egg mixture, and stir. The ratio of egg mixture to water is 1:2.
Add the salt and continue stirring.
Pour the egg mixture into a pan. (The dish should be shallower than the bowl. This will ensure that the eggs will be evenly steamed.
Scrape the froth off the surface of the egg mixture with a spoon. (Be sure to keep the mixture in a bubble-free state before steaming it.)
Cover with plastic wrap. (This prevents steam from dripping into the egg mixture.)
Pour the appropriate amount of water into the pot, bring it to the boil and place the bowl of egg mixture into it.
After steaming for 8 minutes, you can pour a little soy sauce over the eggs. Sprinkle some green onion over the egg and serve.
