4 x 1lb packages of AAA 28 day aged beef, quality hand cut from an inside round roast, unlike regular stew beef which is cut from the neck of the cow.
Aged beef: Aging is a process where beef is hung in a controlled temperature cooler to drain excess water weight, and to let the muscles relax. The longer it hangs the more the muscles relax, the more relaxed the more tender.
Store bought meat is seldom hung more than 10-14 days, a butcher most often ages 21 days, and the best steakhouses always age 35+ days. At PPM all our beef is hung 40+ days to ensure consistent tenderness.
