The food saver was put to use vacuum packaging packaging my pilot bread. The food saver is a marvellous device, I should have bought one years ago.
After packaging the bread, I wanted to seal a mason jar, but didn’t have the proper adaptor, so by accident had a large flour container, upon which the supplied canister adaptor fit perfectly. The mason jar with screw top lightly in place was vacuum pumped. The mason jar sealed perfectly. This device will be ideal for all sizes of mason jars without having to purchase adaptors with different mouth sizes.
