The Grill Friends Steakhouse Burger Press will make you the burger queen or king of your own backyard. Once you use this burger press, you'll see how easy it is to make perfectly shaped patties and never buy pre-made burgers again. The secret is in the "thumbprint" that is pressed into the top of the burger. As the burger cooks and expands, the hole made by the thumbprint flattens out, eliminating the swollen burger forever. Plus you get to decide how big the burgers should be - from a junior quarter pounder to a Chicago steakhouse 3/4 pound. Dishwasher safe.
