Grill or Broil to Your Liking
Accepted doctrine on the matter is that ground beef should be cooked to a minimum internal temperature of 165°F. The only time I'd consider deviating from this rule is if I'd ground the meat myself and knew exactly what was in it. But the nice thing about using a primal cut like beef chuck for grinding your own burgers is that its fat content will keep the burgers nice and moist, even if you do choose to cook them to 165°F.Don't forget the grilled onions!
