Shape the hamburgers into a perfect round shape with the KitchenCraft homemade hamburger press. The press is made of aluminum and consists of two parts. The meat can be placed in the handle-less tray. Then, grab the top part with the handle and press the hamburger together. Remove the hamburger by placing the bottom part upside down on a smooth surface. The press has a non-stick coating, so no meat will stick to it. The hamburger press has a diameter of 11.5 centimeters and can be hand washed after use.
