So I have mentioned a few times about how we dry age a standing rib roast. This is how we do it:
1) Wait for a standing rib roast to go on sale.
2) Unwrap it and put it on a rack
3) Stick it in the fridge and forget it.
That is it!
We do have a small dorm fridge (leftover from college days) we specifically use to dry age meat.
This is the roast we intend to eat for Christmas.
