Pine fixture in kitchen (4)
I believe the answer is:
itch
'pine' is the definition.
(to pine for and to itch for both mean to desire)
'fixture in kitchen' is the wordplay.
'fixture in' indicates a hidden word (the answer is fixed within the clue).
'ITCH' is hidden within 'kitchen'.
(Other definitions for itch that I've seen before include "Longing; anag. of 19" , "Yearn" , "It must be scratched" , "Tickling sensation of skin" , "A strong restless desire" .)
