With the vacuum sealers that have hit the market, they're have been a lot of toys added onto the products. One such device is used for marinating meat. It just looks like a tupperware bin with a nozzle on the lid, and you use a hose to vacuum all the air out. The claim is that this will pull the fibers of the meat apart allowing you to marinade in half the time.
My question is, does this really work or is it just marketing hype? If it does work, is this a better way of marinating?
