Cooked chicken at indoor gathering (8)
I believe the answer is:
tandoori
'cooked chicken' is the definition.
The definition suggests a singular noun which matches the answer.
'at indoor gathering' is the wordplay.
'gathering' indicates anagramming the letters (letters gathered in a new way).
'at'+'indoor'='atindoor'
'atindoor' is an anagram of 'TANDOORI'.
Can you help me to learn more?
(Other definitions for tandoori that I've seen before include "Type of Indian cooking" , "Cooked in an Indian clay oven" , "Indian cooking method" , "Clay oven cooking style" , "Clay-oven cookery" .)
