Ground Kurobuta Pork comes from pure-bred Berkshire pigs, a heritage breed that dates to the 1600s. Kurobuta has more marbling and tastes richer than conventional pork, which has long been bred for reduced fat content. Call it the unconventional pork. Kurobuta stays juicier when cooked which makes it a great way to elevate meat loaf, meatballs, meat sauces and more.
