Preparation Preheat broiler. Toss apples with lemon juice and 2 tablespoons sugar. Melt butter in a shallow baking pan 6 inches from heat. Remove from oven and tilt pan back and forth to coat bottom completely with butter. Arrange apples in 1 layer in pan. Broil apples 6 inches from heat until edges are pale golden and apples are just tender, 8 to 10 minutes. Sprinkle remaining 2 tablespoons sugar over apples and broil until sugar is melted, 1 to 2 minutes. While apples are broiling, boil maple syrup and Calvados 2 minutes. Serve apples and ice cream topped with sauce.
