So art is involved in cookery (5)
I believe the answer is:
roast
'cookery' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'so art is involved' is the wordplay.
'is involved' indicates an anagram (involved can mean confusing or complex).
'so'+'art'='soart'
'soart' anagrammed gives 'ROAST'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for roast that I've seen before include "Reprimand severely" , "Be uncomfortably hot" , "Cook (meat) over a fire" , "Cooked joint" , "Cook (meat) in oven" .)
