Eat dry mix prepared for stuffing (9)
I believe the answer is:
taxidermy
'stuffing' is the definition.
(thesaurus)
'eat dry mix prepared' is the wordplay.
'prepared' indicates an anagram.
'eat'+'dry'+'mix'='eatdrymix'
'eatdrymix' is an anagram of 'TAXIDERMY'.
'for' acts as a link.
(Other definitions for taxidermy that I've seen before include "The art of stuffing and mounting animal skins" , "special stuffing" , "Mounting horses" , "Stuffing practice" , "preservation process" .)
