Italian food, roots mushed up with it (7)
I believe the answer is:
risotto
'italian food' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for risotto that I've seen before include "Perhaps Italian" , "You cook it in stock" , "Savoury rice dish" , "F" , "Italian dish of rice, meat and vegetables" .)
