This deluxe, home-ground blend is a perfect combination of intense flavor and rich, tender texture that will instantly elevate your burger into the big leagues. For this particular burger, we were willing to buy and grind several cuts of meat to create the ultimate blend. Skirt steak was a must for its deep, earthy flavor; boneless short ribs offered tender texture; and sirloin steak tips provided the bold beef flavor that we love in a burger.
