I'm in search of those little squares/rectangles of firm food-grade plastic that typically separate slices of packaged jamón or prosciutto, for the very same purpose: to separate slices of home-made cured pork leg which is just about ready to be vacuum-packed. Last time we did this, they stuck together so this time we want to use the sheets. Any ideas on who carries this in Montreal? I've checked the Aubut catalogue but didn't find any there. Thanks!
