Macerate bananas for afternoon treat? (5,3)
I believe the answer is:
cream tea
'afternoon treat?' is the definition.
(I've seen this before)
'macerate bananas' is the wordplay.
'bananas' is an anagram indicator (bananas can informally mean crazy).
'macerate' is an anagram of 'CREAM TEA'.
'for' is the link.
(Other definitions for cream tea that I've seen before include "Afternoon meal - macerate (anag)" , "Light afternoon meal" , "Devon speciality" , "calorie-packed meal" , "Supposedly civilised afternoon meal" .)
