Fruit leaves perhaps for pudding (4,4)
I believe the answer is:
plum duff
'for pudding' is the definition.
(I've seen this before)
'fruit leaves' is the wordplay.
'fruit' becomes 'plum' (plum is a kind of fruit).
'leaves' becomes 'duff' (I can't justify this - if you can you should give a lot more credence to this answer).
'plum'+'duff'='PLUM-DUFF'
'perhaps' acts as a link.
Can you help me to learn more?
(Other definitions for plum duff that I've seen before include "Sweet" , "Suet pudding" .)
