Using an old German recipe, Boar’s Head Sauerkraut is aged authentically for a crisp, slightly tart, and altogether irresistible taste. It’s a great topping for Boar’s Head Frankfurters and a delightful side for our Kielbasa and Knockwurst; it cooks up wonderfully when used in a variety of recipes. Without a doubt.
