Cold and uncooked crop (4)
I believe the answer is:
craw
'crop' is the definition.
('craw' can be a synonym of 'crop')
'cold and uncooked' is the wordplay.
'cold' becomes 'c' (eg on taps).
'and' says to put letters next to each other.
'uncooked' becomes 'raw' ('raw' can be similar in meaning to 'uncooked').
'c'+'raw'='CRAW'
(Other definitions for craw that I've seen before include "Crop the unacceptable sticks in" , "Bird's crop" , "throat" , "Gizzard" , "Bird's pouch for storing food" .)
