Aunt Sal chopped up fruit (7)
I believe the answer is:
sultana
'fruit' is the definition.
(sultana is a kind of fruit)
'aunt sal chopped up' is the wordplay.
'chopped up' is an anagram indicator.
'aunt'+'sal'='auntsal'
'auntsal' is an anagram of 'SULTANA'.
(Other definitions for sultana that I've seen before include "Sovereign's mother perhaps" , "Dried pale yellow seedless grape" , "fruity little thing" , "Shrivelled up" , "Sovereign's mistress" .)
