Food for a violinist? Only partly (7)
I believe the answer is:
ravioli
'food' is the definition.
(I know that ravioli is a type of alimentary paste)
'for a violinist? only partly' is the wordplay.
'only partly' indicates a hidden word.
'RAVIOLI' can be found hidden inside 'for a violinist'.
(Other definitions for ravioli that I've seen before include "Small pasta cases with savoury fillings" , "Pasta envelopes with savoury filling" , "Italian dish (1)" , "Filled pasta envelopes" , "Filled envelopes of course" .)
