Cabbage available in Dutch outlets (4)
I believe the answer is:
chou
'cabbage' is the definition.
(I know that cabbage can be written as chou)
'available in dutch outlets' is the wordplay.
'available in' says the answer is hidden in the clue.
'CHOU' is hidden in the letters of 'dutch outlets'.
(Other definitions for chou that I've seen before include "Cabbage - ornamental rosette - cream bun" , "Cabbage - Chinese imperial dynasty" , "Pet" , "Cabbage-shaped pastry" .)
