The photo below is an untrimmed packer, 16 pounds, Select grade, from Cash and Carry. I have done nothing but remove the cryo.
I can tell you that is flopped a little in the overly tight cryo, but, by pressing and lifting it, it had a 'soft feel' to the meat. You sort of have to learn to feel for it. This brisket was cooked for someone else, and the report back, was that after reheating, I had cooled it for transit and due to delays in delivery, the brisket was meltingly tender.
