The microwave has given us as an easy way to cook all types of food, including eggs. The cooking period can be exactly timed, allowing peace of mind and perfectly cooked eggs. Although using a microwave to soft-boil your eggs may take as much preparation time as the hob method, it doesn't require any supervision once the cooking time has been set. With the proper cooking time, your microwaved soft-boiled eggs should result in a firm egg white with a runny yellow yolk.
Coat the inside of the cup or bowl with melted butter. Crack the egg into it, then gently pierce the yolk with the wooden toothpick. Creating an opening in the membrane will allow the steam to escape, otherwise the yolk will explode from the pressure.
Cover the top of the cup gently with cling film. Leave one small corner open to allow for escaping steam. Set the microwave to a medium-high setting.
Microwave the egg for one minute, then let it stand for another minute -- the egg continues to cook after it is removed from the microwave, and it will be initially undercooked unless it sits for a minute. Remove the cling film and serve.
If you have high cholesterol levels, instead of coating the cup in butter, extra virgin olive oil or unsaturated margarine can be used.
Don't microwave eggs in their shell unless it is in a device specifically designed for that purpose; otherwise, this could result in exploding eggs and potential injury.
