It's sweet and most elevating (6)
I believe the answer is:
raisin
'it's sweet' is the definition.
I know that 'sweet' relates to this answer.
'most elevating' is the wordplay.
'most' means to remove the last letter.
'elevating' becomes 'raising' (raising is a kind of elevating).
'raising' with its last letter taken off is 'RAISIN'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for raisin that I've seen before include "Dried grape used in cakes" , "sultana, say" , "Fruit for the Christmas cake" , "A dried grape used in cake" , "A dried grape, nice in cake" .)
