If this doesn't work you either have the heat too high or need a better frying pan. Practice with different amounts and you'll have a dish you can serve hot or cold for breakfast, lunch or supper. Once cold you can cut it into slices to take on a picnic. It's a good to eat before an exam or facing trials of any kind and makes a perfect dish for unexpected guests.
I grew fond of this when staying at a little hotel in Seville. An odd job man called Gonzales used to make it for our lunch. The hotel has sadly closed but the recipe lives on bringing back memories of the time when I was first married.
