Any burger pro will tell you this is THE best burger mix. A combination of 10% short rib, 25% brisket and 65% chuck creates a flavorful grind with the optimal ratio of fat to lean of 80/20. Made from whole muscles only – no trim or byproducts added. Midwest Black Angus cattle grown exclusively for Allen Brothers. Enjoyed at some of the best restaurants in the country, but equally at home on the backyard grill. Individually packaged patties.
