This is not really a food phrase. The real phrase dates back to middle English and the English Navy.
Muster (not mustard) by definition means "representative specimen" - in the English Navy calling to muster was a reference for the drills and the time it took to get all hands on deck (for evacuation or battle). Making the muster cut means that you and your team were good/fast enough to pass the drill. Those who passed made the muster cut, those who failed had to re-drill and possibly got additional duties.
