I saw this on Face book on a meat site there, never saw steatosis this bad

Muscular steatosis is a condition where muscle fibers have been replaced by fatty deposits, which creates a striking appearance in cuts of meat with it. Sometimes this condition is simply called “steatosis,” “callous,” “calloused lean” (other spellings include “callus,” “woody callused”), or because it is observed sometimes in the ribbed carcass, in this case, it is called “calloused ribeye.”
