Deity takes turn with a dairy product (5)
I believe the answer is:
gouda
'dairy product' is the definition.
(I know that Gouda is a type of cheese)
'deity takes turn with a' is the wordplay.
'deity' becomes 'god' (a deity is a god or divine being).
'takes' indicates putting letters inside.
'turn' becomes 'u' (a 'U-turn' is a kind of turn).
'with' is a charade indicator (letters next to each other).
'god' enclosing 'u' is 'goud'.
'goud'+'a'='GOUDA'
(Other definitions for gouda that I've seen before include "Dutch town" , "Mild Dutch cheese" , "It comes from Holland" , "Round Dutch cheese" , "type of cheese" .)
