In addition to saving you time and money, a vacuum sealer is also ideal for cooking with the sous-vide method. This is a technique in which food is vacuum-sealed and cooked in a temperature-controlled bath of water at low heat for a long time. This method allows you to cook foods evenly to a specific temperature without sacrificing moisture or flavor. Try it with steak, fish, eggs, veggies, and more. Here are some of our favorite vacuum sealers available now.
