Salt I love to put on fruit (6)
I believe the answer is:
iodate
'salt' is the definition.
(I've seen this before)
'i love to put on fruit' is the wordplay.
'i love' becomes 'io' (I've seen this in other clues).
'to put on' says to put letters next to each other.
'fruit' becomes 'date' (date is a kind of fruit).
'io'+'date'='IODATE'
(Other definitions for iodate that I've seen before include "Salt of iodic acid" , "Salt; to aide (anagram)" .)
