Food with wine turning up is soup (7)
I believe the answer is:
chowder
'soup' is the definition.
(I've seen this before)
'food with wine turning up' is the wordplay.
'food with' becomes 'chow' (I am not sure about this - if you are sure you should believe this answer much more).
'wine' becomes 'red' (red wine is a kind of wine).
'turning up' is a reversal indicator.
'red' in reverse letter order is 'der'.
'chow'+'der'='CHOWDER'
'is' is the link.
Can you help me to learn more?
(Other definitions for chowder that I've seen before include "possible first course?" , "Clam stew, soup" , "clammy" , "dish in America" , "Rich soup with fish, clams etc." .)
