Whip up the EGGS, add 1 dessertspoonful of water for each egg, as in the previous recipe; mix in the cheese, a little made mustard, and pepper and salt. Heat the butter in a frying-pan or small stewpan. When hot stir in the mixture of egg and cheese. Keep stirring it with a knife, until it becomes a smooth and thickish mass. Put on hot buttered toast, and serve. This is an extremely tasty French dish. The mixture, when cold, is excellent for sandwiches.
