Grease 4 ramekins with butter, preheat oven to 180c. Melt the butter in a small saucepan and add the flour. Cook for a minute or two and whisk in the milk gradually so no lumps form. Pour the mixture into a bowl and add the crab, cayenne pepper and cheese.
Separate the egg whites from the yolks and in a clean bowl whisk the egg whites until it forms a stiff peak. Now that the crab mixture has cooled down add the eggs yolks that have been gently mixed, then fold in the egg whites.
Divide the mixture between the 4 ramekins and place in a deep ovenproof dish with enough boiled water to reach up to halfway of the ramekins. Cook in the oven for 20 mins and serve straight away with your salad.
