These bars are quick to make, extremely satisfying, and quite versatile. You can serve them as bars for an afternoon snack, or for dessert with a scoop of ice cream. Vanilla ice cream complements any flavor of jam, but experiment with unusual combinations: Strawberry preserve bars with chocolate ice cream. Blackberry preserve bars with blackberry ice cream. Cherry preserve bars with butter pecan ice cream. Have fun with it and see what you come up with.
