Gristle found in horrid garlic tea (9)
I believe the answer is:
cartilage
'gristle' is the definition.
('cartilage' can be a synonym of 'gristle')
'horrid garlic tea' is the wordplay.
'horrid' indicates an anagram.
'garlic'+'tea'='garlictea'
'garlictea' is an anagram of 'CARTILAGE'.
'found in' is the link.
(Other definitions for cartilage that I've seen before include "Gristle" , "Tough white flexible tissue attached to bones" , "bodily tissue" , "Connective tissue in joints" .)
