Thanks for all the information.
Because of this page I was introduced to the Vacuum Express Tumbler, which I intend to purchase. From what I took from the videos I viewed, I would just need to add the spice, water or glycerin, and the meat to the drum and sit back and wait? Also, I remember seeing the post or review on the Glycerin but cannot locate it now. Would the added amount be the same as if it were water?
