These hamburgers with meat from short ribs and sirloin steak make the juiciest, most delicious, best burgers ever!
11 oz. boneless short ribs, large pieces of fat trimmed off
11 oz. sirloin steak, large pieces of fat trimmed off
Coarse salt
4 buns of your choice
Dijon mustard, whole-grain mustard, mayo or ketchup
Romaine lettuce leaves
Sliced tomatoes, for serving
Onion slices
Your choice of cheese
Blue cheese
Have your butcher cut both meats into small pieces and grind through the large holes of a meat grinder. If you have a meat grinder, you can do this yourself.
Divide into 4 equal parts and form into 4 patties. Push the center of the patty down a little to make a well. This will prevent the burger from getting a domed top like a muffin. Don't pack meat too tightly.
Preheat grill to medium-high heat. Season both sides of the burgers with salt, then grill 2 1/2 minutes on each side for medium-rare, placing cheese on burgers at the last minute. Avoid the temptation to push juices out of burger while cooking. Transfer to a plate.
Grill tops and bottoms of buns until toasted about 30 seconds.
Serve with your favorite toppings.
