I've struggled with plastic wrap and tin foil to cover all sorts of food. Something always gets spilled or spoiled. I know exactly what would fix my problem: one lid that fits all the various bowls and pans I have, that provides a solid seal, and that keeps food fresh. While my this might sound like a lot to ask for, Kuhn Rikon has provided exactly this with its MagicCover.
The MagicCover is the perfect lid; all you have to do is place it on the container you want to seal and press down on the center of lid. You don't have to apply much pressure--just a little is enough to create a light vacuum seal. And it's equally easy to remove, unlike the lids of many food containers. The MagicCover is made from high-quality silicone and stainless steel. It's dishwasher-safe, and can be used in the oven, microwave, refrigerator, and freezer. It's sturdy, as well; you can stack bowls sealed with the MagicCover without any worry. The MagicCover also can double as a trivet or splatter guard. It's priced at $17.95 and is available in a variety of sizes.
