Stews: a tiny bit of gristle stuck in teeth (7)
I believe the answer is:
tagines
'stews' is the definition.
(I've seen this before)
'a tiny bit of gristle stuck in teeth' is the wordplay.
'tiny bit of' says to take the initial letters.
'stuck in' is an insertion indicator.
'teeth' becomes 'tines' (I am not sure about this - if you are sure you should believe this answer much more).
The initial letter of 'gristle' is 'g'.
'a'+'g'='ag'
'ag' placed within 'tines' is 'TAGINES'.
Can you help me to learn more?
(Another definition for tagines that I've seen is " stews".)
