thanks. i'm not planning on adding any fat to my burger meat. they've always asked at the processor if i wanted fat added and i've always said no.
I usually only worry about freezing when working with sausage (the added fat is the reason) and I do just as described above. I use meat lugs (get a few with lids) and if you put one in a freezer in without a lid with decently cold meat to start it will start to ice on the top and bottom in a half hour or 45 minutes. Unworkable for sure after 2 hours (although the middle would probably not be frozen at all).
If working with lean, I just make sure it is cold (not warm, but not icy, either) and keep the grinder fed well so it is grinding quickly and moving the meat through so as not to get warm.
