Little Sarah and Edward like some nuts (6)
I believe the answer is:
salted
'like some nuts' is the definition.
(I've seen this before)
'little sarah and edward' is the wordplay.
'little' means to remove the last letter (the word is not quite complete).
'sarah' becomes 'Sall' (Sally is a common pet form of Sarah).
'and' says to put letters next to each other.
'edward' becomes 'ted'.
'sall' with its final letter taken off is 'sal'.
'sal'+'ted'='SALTED'
(Other definitions for salted that I've seen before include "cured" , "Seasoned, given piquancy; (of meat) preserved" , "Like some nuts" , "Lasted, being preserved" .)
