Proculation Proculation:
Well, tell us the basic of you recipe and technic !
I always add a LITTLE milk, never too much and cook it very slow so that it cooks uniformally.
Milk bad. It's cheating.

Separate your yolks and whites. Whip the whites hard, with a pinch of salt until they are fluffy, then add the yolks. I 'baste' the omlette too. Pour in a couple tablespoons water, and cover the pan for a minute or two. The eggs will be very large and fluffy.
Then add the fillings and proceed as normal.
