Cook, covered, over medium-low heat for 5 to7 minutes or till apples are tender, stirring occasionally. Drain in a colander.
Transfer apples to a small bowl.
Gently stir cinnamon into cooked apples. In the same small saucepan combine brown sugar, light-colored corn syrup, and margarine or butter. Cook and stir over medium heat till mixture just comes to a boil. Remove from heat. Pour mixture into a 2-quart square baking dish.
