Most elevating thing you can eat? (6)

I believe the answer is:
raisin
'thing you can eat?' is the definition.
I can't judge whether this definition defines the 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 removed is 'RAISIN'.
Can you help me to learn more?
(Other definitions for raisin that I've seen before include "A dried grape, nice in cake" , "Partially dried grape" , "An iris (anag)" , "Large dried grape" , "sultana, say" .)
