Urge to get into the kitchen (4)
I believe the answer is:
itch
'urge' is the definition.
(I know that urge can be written as itch)
'into the kitchen' is the wordplay.
'into' says the answer is hidden in the clue.
'ITCH' is hidden in the letters of 'kitchen'.
'to get' is the link.
(Other definitions for itch that I've seen before include "Tickling sensation of skin" , "Burning" , "Hankering" , "Skin sensation; desire" , "minor irritant" .)
