Grass-fed beef liver is one of the most nutrient-dense foods you can put on your plate — a real source of vitamins A, B6, B12, iron, zinc, and folate. The flavor is stronger than a typical cut, which is why most people do best with simple preparation: pan-fry with butter and onions, or slice thin and cook quickly to avoid toughness. Raised on Old Time Farm in Mercer County by Shel Oswald. These Old Time American Milking Devon cattle are raised in family groups from birth to harvest— no hormones, no antibiotics, no GMOs, 100% grass-fed and grass-finished, USDA processed at a local family butcher shop, vacuum packaged and frozen. Delivered the first Saturday of the month to Pittsburgh, the North Hills, Cranberry Township, Grove City, Butler County, and surrounding areas. Free delivery on orders over $195.
