Beat the eggs until foamy. Add the milk, the 1 teaspoon of sugar, salt and pepper and mix well.
Melt butter in a heavy skillet (preferably one used only for omelet making). Add the egg mixture and let cook over a low flame. As omelet cooks, lifth the edges toward the center and tip the pan to cook all parts equally. Cool until firm but not dry.
Fold over and turn omelet onto a hot, butter platter. Sprinkle with the 2 tablespoons of sugar and add the brandy which has been ignited. When the flame dies, garnish with orange sections or thin slices of orange.
