In cuisine, an omelette or omelet is a dish made from beaten eggs quickly cooked with butter or oil in a frying pan. It is quite common for the omelette to be folded around a filling such as cheese, chives, vegetables, meat (often ham and/or bacon), or some combination of the above. To obtain a fluffy texture, whole eggs or sometimes only egg whites are beaten with a small amount of milk or cream, or even water, the idea being to have "bubbles" of water vapour trapped within the rapidly cooked egg.
