Well, I have come to find out that I had previously been cooking this burger under the wrong name. A burger made with two patties and cheese in the middle is in fact called a Juicy Lucy....or so says The Travel Channel's Man vs. Food. Just having the name correct added that special bit of magic that makes this one of my favorite burgers!
I used some good ol' ground beef (nothing fancy here) and made two fairly thing patties. Next I folded up a piece of Amercian cheese into fours and placed it in the middle of one patty.
After that I formed the two patties together into one (and repeated the process 4 times) and then cooked the burgers on the grill (at about 400 degrees) for 8-9 min on one side and then flipped to the other side for an additional 8-9 min. I let the burgers and primarily the cheese, cool for a few min and then served with some sweet potato fries. Careful, the cheese stays warm for quite a while (which is great)! Hard to beat a good homemade burger!
