It might be tempting to buy that perennial can of jellied cranberries—there might be one left over from Thanksgivings past in your cupboard right now—but there’s really no comparison between that and this handmade supper trimming. Just watching the magic as it jells might be enough. And don’t limit its uses to a turkey dinner or leftover sandwich; the tart character of cranberry sauce lends itself to experimentation. Spoon it over yogurt for a morning pick-me-up; mix it into a pound cake recipe; use it as a topping for burgers or waffles or add it to ketchup for a tangy dip for barbecue.
