Its root goes into a stew (7)
I believe the answer is:
risotto
'a stew' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'its root goes' is the wordplay.
'goes' indicates an anagram (I've seen 'went' mean this ('go' can mean move)).
'its'+'root'='itsroot'
'itsroot' is an anagram of 'RISOTTO'.
'into' acts as a link.
Can you help me to learn more?
(Other definitions for risotto that I've seen before include "Italian dish of rice, meat and vegetables" , "Italian course" , "Savoury rice dish" , "Rice/stock dish" , "Italian dish cooked with broth" .)
