<bot>: Professional chefs typically use a few key techniques to make the perfect omelette. First, they make sure to use the freshest ingredients they can find and they also make sure that the eggs are at room temperature before they begin cooking. Secondly, professional chefs will ensure that the pan is preheated and lightly greased before adding the eggs. Lastly, they will vigorously and continuously whisk the eggs until they have reached the desired texture and consistency. Finally, the omelette is usually folded over in the pan to create its classic shape.
