Serve these easy pear halves warm or chilled. The sweet jelly glaze and dollop of thick cream topping are what make them so good.
Arrange pear halves, cut side up, in an ungreased 13" x 9" baking dish. Stir together ginger ale and next 3 ingredients. Pour ginger ale mixture over pears; sprinkle with 1/4 teaspoon cinnamon. Cover and chill at least 3 hours or overnight.
Remove pears from refrigerator, and let stand at room temperature 30 minutes. Uncover and bake at 350° for 40 minutes.
Melt jelly in a small saucepan over low heat; stir in remaining 1/4 teaspoon cinnamon and 3 tablespoons pan juices.
Remove pears from baking dish using a slotted spoon. Place pears in a serving dish; pour jelly mixture over pears. Serve with Mock Devonshire Cream. Garnish, if desired.
