This Pig Cooking Lid is made of soft silicone with a pig face in the center. This multipurpose lid can be placed in boiling water directly over ingredients to help them cook evenly, releasing steam through the pig's snout. This helps preserve the shape of fragile ingredients by reducing the pressure that boiling bubbles exert on food. It can also be used to cover food in the microwave, and as a grip to open lids. Dishwasher- and microwave-safe. This product was included in Destination: Japan, a MoMA product collection highlighting lifestyle products from Japan.
