I had several gallons of cigilani (sp) small fresh mozz balls, that were donated to an event I catered and were going south, so I drained and froze them in ziploc....BIG friggin' mess....they frozen together into a block of mozz balls.....so freezer space always being a premium around here, next time I'd freeze on a sheet individually separated, then package in a ziploc so they would be easier to use.
