Hi All,
Those cookers which steam the eggs are really convenient. They have a shallow hot plate where you put a bit of water using a measuring cup. Depending how much you use, you can choose how hard-boiled the eggs will be. The cooking stops automatically when the plate goes dry. You can also make an omelet or poached eggs in a small bowl.
It's quick because there is so little water to heat up. In the morning I will start it and then prepare the rest of my breakfast while the eggs are being done.
