So you think whole subprimals from Costco is a fantastic deal. I always buy the full strip loin and cut & vacuum seal myself.
I just cut one up last weekend, was ~$220 (~$30/kilo).
After trimming it all up you get this much fat/chine/etc:
Which just for fun I decided to weigh, and it came in nearly 2Kg exactly.
Fucking $60 just in fat!
Well this is far too valuable to waste, it's in a pot and rendering down as I type this.
