Sounds good. She has put some shredded cheese into a bell jar and vacumned that. So far, it looks like that worked. Do you store the sealed shredded cheese in the freezer or the frig? Another thing that was a slight problem was she dehydrated some cooked angle hair pasta and then vacumned it. The pasta poked holes in the bag and that did not work. But if she put the pasta into an open ziplock bag it vacumned just fine -- except that the pasta got broken up some. Something else we are wondering -- sealing up various Christmas cookies.
