My first dry aging experiment went very well: 45-days, a less-trimmed piece of bone-in, choice-grade ribeye, in a dorm fridge with fan and salt block. Tasted great, normal moisture loss, and no rot.
Now that I'm confident it works, I'd like to source some higher quality product, but I'm having trouble finding any at a reasonable price. Most places want to charge well over $20/lb for prime grade - and I've had an impossible time finding it at a relatively early stage of fabrication (think 107/109). If I could find an early-stage choice for <$10lb, I'd count myself lucky. And untrimmed, $15/lb for prime seems very reasonable. But everything I've found has come within a few dollars of the the $35/40 you pay for dry-aged from a butcher, when part of the point of the whole project was to save some money!
So, help me out. Anyone who's dabbled here have any tips? Most appreciated would be a butcher/processor recommendation from you Chicagoland Chefsteppers.... Thanks!
