What to do with it?
Farkin COOK it bro!
I have a family of 6 and with the extended family, THAT would make for a real nice prime rib roast dinner, and a CHEAP one at that!
Or, as said....cut some nice steaks off of it and use a smaller roast if you're not feeding as many as I usually do when the family comes over (which is usually around 15).
DRY AGE, DRY AGE, DRY AGE!
Like gtr did this last Christmas.....
