If you've ever used half a lemon (read: if you cook at all), you know how annoying it can be to try to keep the unused portion fresh. Do you throw it in a plastic baggie? Or cover it in plastic wrap? You don't want the lemon to go to waste, but you also don't want to fill the garbage with unnecessary trash.
Enter: this set of Food Huggers.
Crafted out of BPA-free, food-safe silicone, the set (a steal for less than $9) comes with four different sizes, each stretching to fit the desired item and forming a tight seal that protects the food from air, moisture, and the like. They're dishwasher- and microwave-safe, nest together for compact storage, and will save you from having to drop cash on plastic wrap and bags.
Farberware Food Huggers, $9 for four
And while the Food Huggers are great for items like tomatoes, onions, lemons, and limes, they can also stretch to cover containers, so you can use that old bowl — even though you lost the lid to it back in the early 2000s.
