Yellow turkey (5)

I believe the answer is:

lemon

This clue is a double definition.

'yellow' is the first definition.
(I know that lemon is a type of yellow)

'turkey' is the second definition.
(both can mean a failure or flop)

(Other definitions for lemon that I've seen before include "A fruit; a worthless item" , "leaving bitter taste?" , "Washout" , "Fruit - 11 (anag)" , "Fruit - as an answer it's unsatisfactory" .)

I've seen this clue in The Times.
