Cooking method, first of three broadcast on radio (8)
I believe the answer is:
tandoori
'cooking method' is the definition.
The definition suggests a singular noun which matches the answer.
'first of three broadcast on radio' is the wordplay.
'first of three' becomes 't' (1st letter of 'three').
'broadcast' indicates an anagram (letters scattered or cast around).
'on'+'radio'='onradio'
'onradio' is an anagram of 'andoori'.
't'+'andoori'='TANDOORI'
Can you help me to learn more?
(Other definitions for tandoori that I've seen before include "Clay-oven cookery" , "Indian cooking in clay oven" , "Indian-style cooking" , "Indian style of cooking" , "Type of restaurant" .)
