I used to do ribeyes in a week...and they were awesome.
I cut the steaks, put them in a ziplock bag with a couple teaspoons of vietnamese fish sauce and about a teaspoon of
good soy sauce, evacuate the air, and put them in the fridge for 24 hours.
They are then taken out, rinsed off under cold water, patted dry, individually wrapped in cheese cloth, and put back in the refrigerator for 6-7 days. I put a salt slab in the bottom of the fridge to pull the moisture out of the air and just lay the wrapped steaks directly on the wire shelves.
The fish sauce kicks the enzyme action into high gear and reall imparts no flavor, (if you don't leave it on the meat for 3 days like some suggest). It gives you a dry aging in about 1/4 of the time. Try a couple while the rest are aging.
