Instructions

1. 1

   Preheat the grill on its highest setting. Place the egg yolks in a small bowl and whisk until creamy. Season to taste with salt and pepper, add 2 tbsp water, and whisk again. Wash the whisk in hot soapy water and dry, then use to whisk the whites in a large, clean bowl, until they form soft peaks.

   
   

2. 2

   Heat the butter in a non-stick frying pan over a medium heat. Meanwhile, using a large metal spoon, quickly fold the egg yolks into the egg whites with half the cheese, taking care not to over-mix.

   
   

3. 3

   When the butter is foaming, pour the mixture into the pan, shaking the pan to make sure the mixture is evenly distributed. Cook the omelette for 1 minute, then slide a palette knife around the edge to loosen it from the pan. Scatter the omelette with the remaining cheese, and the ham, and place under the hot grill for 1 minute to allow the surface to cook.
