Beat the eggs lightly. Add the milk.
Combine the flour, sugar and salt. Stir the flour mixture into the egg mixture, stirring in the ½ cup of cream as you mix.
Fry the apple slices in butter in a skillet.
Cover the bottom of an oven-proof baking dish, or heavy skillet, with apples. Pout the batter over slices and bake in a preheated 500° oven. When nearly done (20 or 25 minutes, or until the pancake looks like a cooked omelet), remove from oven and sprinklehere and there with a mixture of sugar and cinnamon to taste. Place dabs of butter on the pancake and return to oven until browned.
Just before serving, sprinkle with lemon juice, and cut into triangles.
