One cold summer in France with a cold drink (3,3)
I believe the answer is:
ice tea
'cold drink' is the definition.
(I've seen this before)
'one cold summer in france with a' is the wordplay.
'one' becomes 'i' (Roman numeral).
'cold' becomes 'C' (eg on taps).
'summer in france' becomes 'ete' (').
'with' is a charade indicator (letters next to each other).
'i'+'c'+'ete'+'a'='ICE TEA'
(Other definitions for ice tea that I've seen before include "refreshing drink" , "Cold summer drink" , "Cool non-alcoholic drink" , "Chilled drink flavoured with lemon" , "refresher" .)
