He has good taste to eat these when cooked (8)
I believe the answer is:
aesthete
'he has good taste' is the definition.
(I've seen this before)
'eat these when cooked' is the wordplay.
'when cooked' indicates anagramming the letters.
'eat'+'these'='eatthese'
'eatthese' with letters rearranged gives 'AESTHETE'.
'to' is the link.
(Other definitions for aesthete that I've seen before include "Art-lover" , "One is particularly appreciative of beauty" , "Someone sensitive to beauty in art" , "Self-styled art lover - the tease (anag)" , "Person appreciating the beauty of art" .)
