Put the dishes in a saucepan, in which we pour water. The pot should be higher than the omelet dish, so that it can be safely covered with a lid. Water should be at the level of the contents of the dishes with the omelet. So the water will boil and not fall on the omelet, otherwise it will turn blue. Put the pan on the fire, cover with a lid. When the water boils, reduce the heat to a minimum. DON'T OPEN THE LID! It gathers the condensate. After 30 minutes, the 4-egg omelet is ready! You can eat it directly from this dish, or you can put it on a plate. With a knife, we draw around the wall of the dishes with the finished omelet, separating it from the walls, if it is stuck somewhere.
