Sometime, you might want to give my very old-fashioned family method for cooking a hamburger a try...
Preheat a cast iron pan with a dusting of Kosher salt for about 10 minutes (that's why there's no salt added to the meat), add the burgers and cook to the desired state of doneness... it'll give you a great crust not unlike a grill. And the salt will not draw out any of the juices by being mixed into the meat. And believe it or not... the burger does NOT taste overly salty.
