Stewed neck, hit in cookhouse (7)
I believe the answer is:
kitchen
'cookhouse' is the definition.
(thesaurus)
'stewed neck hit' is the wordplay.
'stewed' indicates an anagram.
'neck'+'hit'='neckhit'
'neckhit' anagrammed gives 'KITCHEN'.
'in' is the link.
(Other definitions for kitchen that I've seen before include "Room for preparing meals" , "food preparation area" , "Cook's room" , "Room with proverbial heat" , "Room with cooking facilities" .)
