The"magic" thawing sheets I believe are just aluminum...just put the item on an upturned aluminum pan to
thaw.

For bulk ground meats, flatten them out into quart or gallon Ziplock freezer bags, filling the bags evenly
into the corners, and freeze flat. They thaw in a jiffy in the bag, or you can break off frozen chunks if you don't
need it all at once.
