Steak order (6)
I believe the answer is:
medium
'steak order' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for medium that I've seen before include "Average - means of communication" , "Intermediary with the spirit world" , "Spiritualist in charge of seance" , "Conductor of seances - just average" , "TV, say" .)
