When you need to save food for long periods of time, one of the smarter ways is to vacuum-seal it. This gets out all of the air, which helps to preserve the contents for much longer than other traditional storage methods. Unfortunately, doing this usually requires the use of special hardware and bags, which can cost more than you really want to spend. Of course, there’s always the DIY route, if you want to get the best of both worlds.
Over on MAKE there is a great little guide that shows you how to vaccum-seal your everyday Ziploc bags, using nothing more than a hand-powered vacuum pump. The method involves placing one bag inside of another, getting all of the air out, and then sealing the inner bag. It’s nearly as effective as the more expensive machines and bags you’ll find on the market, for a fraction of the price.
