Consumes a set recipe (4)
I believe the answer is:
eats
'consumes' is the definition.
(eating is a kind of consuming)
'a set recipe' is the wordplay.
'recipe' indicates an anagram.
'a'+'set'='aset'
'aset' anagrammed gives 'EATS'.
(Other definitions for eats that I've seen before include "worrying" , "Commonly, they eliminate" , "Sate (anag.)" , "Devours - food" , "Takes food" .)
