Step 1 In a medium saucepan, combine the apples, cinnamon, brown sugar and a pinch of salt over low heat. Cook, stirring until the apples are tender but not mushy, 8 to 10 minutes. While the apples are cooking, combine the water and cornstarch in a small bowl. Add the cornstarch mixture to the apples and increase the heat to high, stirring until the liquid bubbles and thickens. Remove from heat and hold in a warm place.
