(Turned) sour (6)

Ross

I believe the answer is:

rancid

(Other definitions for rancid that I've seen before include "Smelly and going bad" , "Smelling bad like stale fat" , "(Of fat/oil) stale and foul smelling" , "Stale, with an offensive smell" , "Sour like stale fat" .)

I've seen this clue in The Guardian.
