I have a frozen wagyu brisket that I bought a few months ago for a contest coming up in a few weeks. Does anybody have any idea on how long this sucker will take to thaw. It's about 13lbs. Is there any harm in letting it sit thawed out in a fridge for a week or so? In the past I've wet aged briskets for 2-3 weeks in the fridge, but not sure if that's ok after it's been frozen.
