I am dry aging my 17 pounder for Christmas Eve. 9 Days.
You can dry age up to 21 Days, this process imparts a stronger flavor, the enzymes break down making a even more tender roast.
You must start w choice to prime ( this is choice from Costco)
I change the cheesecloth every 2-3 days.
You must wash w water first, then dry completely.
Before roasting, trim all the areas that are crusty, oil it, spice rub(your choice).
Yummy!!
