Slice squash into 1-inch thick rings, discarding seeds. Arrange in shallow baking pan. Bake, covered, in a 350° oven for 35 to 45 minutes, or until just tender. Season with salt and pepper. In medium saucepan, combine brown sugar, cornstarch, cinnamon, and nutmeg. Stir in apple cider. Cook, stirring constantly, until thickened and bubbly. Stir raisins, butter and maple flavor into the sauce. Spoon over squash. Continue baking, uncovered, for 15 to 20 minutes, or until squash is tender.
