A body member of a press has a peripheral imperforate side wall and an imperforate end wall, the end opposite from the imperforate wall being open. The press has a lid-engaging portion capable of abutting a severed but remaining lid of a can and utilizing the lid as a pressing plate to press liquid from food in the can upon relative forced telescoping movement of the body member and the can. The lid engaging member supports a magnet capable of magnetically attracting the lid and pulling the lid out of the can upon completion of the pressing operation. The magnet can also serve to attach the press to a metal surface. The can engaging area of the press is shaped to fit the contour of the lid of a can.
