Old bouncer resolved description of high quality cook (6,4)
I believe the answer is:
cordon bleu
'description of high quality cook' is the definition.
'cordon bleu' can be an answer for 'cook' (cordon bleu is a kind of cook). I'm not certain of the 'description of high quality' bit.
'old bouncer resolved' is the wordplay.
'resolved' indicates an anagram.
'old'+'bouncer'='oldbouncer'
'oldbouncer' with letters rearranged gives 'CORDON BLEU'.
Can you help me to learn more?
(Other definitions for cordon bleu that I've seen before include "Of the highest culinary order" , "(Of cookery) very high standard" , "Of a very high standard (food)" , "Old bouncer (anag)" , "High-class cookery" .)
