This bright and not-too-sweet, four-ingredient jam is amazing on toast, of course, but spread your wings and try it on pork chops, with roasted chicken, or even as a dessert topping with ice cream and cookies. Look for Pomona’s Universal Pectin in the baking aisle in the grocery store. If you don't want to process your jam, divide it into pint- or half-pint containers and store them in the freezer and thaw them as needed.
