How do you seal jars at home?

Chef's answer
Sealing
  • Immediately each jar is filled, cover the top with a waxed disc (wax side down) or piece of parchment so that it lies flat on the surface and excludes any air. ...
  • Then place the lid on the jar while the jam is still hot.
  • Jars can be sealed with cellophane secured over the jar with a rubber band.

    Vacuum sealing protects food from dehydration and freezer burn. Freezer burn occurs when water gets into your food. The vacuum bag keeps your food from contact with the air, so moisture cannot evaporate, making it an excellent barrier from the elements.
    Prepping the steaks in advance by taking them out of the store packaging before vacuum sealing them, and then seasoning them, will help save room in the freezer.
