We all know you can save money by buying food in bulk, but that's not always good for food that has a short shelf life, like fresh greens. The problem is exacerbated for people who live alone, because even a small package can start to wilt before you can eat it all. But if you happen to own a SodaStream, you've got it made. The device was designed to add carbon dioxide to drinks to make them carbonated. It can do the same to a bag of vegetables.
The foodies at America's Test Kitchen divided a package of assorted lettuces into two plastic bags. They stored one the way anyone would. Then they inflated the second bag with carbon dioxide from a SodaStream. The result was that the regular bag of lettuce began to wilt after five days, while the "carbonated"bag lasted nine days before it began to wilt!
In a regular kitchen we would expect that you would have to re-inflate the bag with carbon dioxide after getting lettuce out for your meals, but that's a small price to pay to make your greens last almost twice as long. And you can stop regretting giving shelf space to a SodaStream, since it is no longer a single-use kitchen gadget. -via Kottke
