In water myself, no freezer burn. Not that much more space, just enough to cover the fillets and lay them flat until frozen. Stack nicely. What takes up space is those frozen chickens, told Ann several years ago - they have to go. I have a large freezer in my shop just for crappie filets, red snapper fillets my son brings me, peeled crawfish, alligator, rib eyes on sale, choice cut briskets, etc. She has to make do with the refrigerator/freezer in the house.
