Cooked, the ray is gross (6)
I believe the answer is:
earthy
'gross' is the definition.
(I've seen this before)
'cooked the ray' is the wordplay.
'cooked' indicates an anagram.
'the'+'ray'='theray'
'theray' anagrammed gives 'EARTHY'.
'is' is the link.
(Other definitions for earthy that I've seen before include "Coarse; unsophisticated" , "Hearty (anag)" , "Like soil; uninhibitedly direct" , "Coarse like the soil" , "Unrefined - the ray (anag)" .)
