I used to do them in the microwave. Use a plastic ramekin dish, very well greased with butter or marge. Put the egg in and prick the yolk with a cocktail stick(this will stop it exploding). Put in the microwave and cover with a bit of kitchen towel (in case you didn't prick it well enough!!) and cook for 30 -45 secs according to how you like it (takes a bit of practice to get the time just right). Remember, eggs carry on cooking after you remove them from the heat. This is true of all cooking, but especially prevelent in microwaves, so bring them out a bit underdone.
