This boneless item shall consist of the outside muscles (biceps femoris and semitendinosus) from the leg. The inner shank (gastrocnemius) may remain. However, the flexor digitorum superficialis muscle, or mouse as it is often referred to, shall be excluded. The popliteal lymph gland and surrounding fat in excess of 0.25 inch (6 mm) in depth shall also be excluded.

The purchaser may specify outside form two legs be reversed and netted or tied so that the boned surfaces when placed together produce a uniformly thick roast. If this option is specified, the purchaser may also request the item to be divided into approximately equal portions by a straight cut(s) at a aright angle to the length of the item.
