Why are some common cuts of meat not available, like sirloin and filet mignon?
By Jewish law we are not allowed to eat the hind quarter of animal because of the large nerve that runs through it. Some communities, like Sephardim, have specially trained workers who can remove this nerve with great skill. It is thought prohibitively expensive in labor to remove this nerve and thus, in Ashkenazic meat plants, the common practice is not to process meat from the hind quarter for sale to the kosher market. Loin cuts like sirloin and tenderloin are produced from the hind part of the animal and so these cuts are not available on our site.
