Sweet Omlette

OK, sounds a bit odd, but I found this in a Nigel Slater recipe book last night, when I was craving something sweet...

Ingredients
3 eggs, seperated
1 tbsp sugar
Knob of butter
Filling of choice


Method
Whisk the egg yolks and sugar until thick.
Whisk the whites in a seperate bowl until they form firm peaks.
Fold the whites into the yolk mixture with a metal spoon.
Melt the butter in a non-stick omlette/frying pan and cook over medium heat until the bottom is set.
Place under a hot grill to cook the top.

Serve with filling of your choice: warm jam, fruit etc. I used about 3 tablespoons of homemade berry jam, slightly warmed in the microwave!
