Peel and halve apples and remove the core. Cut apple halves into slices. Boil up lemon juice, sugar, Calvados and some water. Add the apple slices and cook for about 3 minutes. Take out and let cool down. Separate the egg.
Mix cream double and egg yolk. Beat the egg white until stiff and fold into the egg yolk. Place the apple slices in small ovenproof dishes. Mix the double cream with the cinnamon and place it on the apple slices and sprinkle with almond slivers. Place the moulds in the preheated grill and grill until they are lightly browned. Serve decorated with lemon balm
