Small bowl can put an egg, filled with water; large bowl put two eggs, filled with water. You can usually look at the color, not too white on the line. Put warm water / white water these seem to have little impact.
Stew it on high heat, 10 minutes after the water boils, you can (the surface looks very slippery on the cooked, and then stewed is not good, very old)
Put the milk well, it is not clear. Sometimes too much or too little salt is not cooked.
