Ignoring odd bits, irradiate a dish in India (5)
I believe the answer is:
raita
'dish in india' is the definition.
(type of Indian side dish)
'ignoring odd bits irradiate a' is the wordplay.
'ignoring odd bits' indicates alternate letters (letters in odd-numbered positions removed).
The alternate letters of 'irradiate' are 'rait'.
'rait'+'a'='RAITA'
(Other definitions for raita that I've seen before include "Indian dish of chopped cucumber and yoghurt" , "Indian side dish of yogurt and chopped cucumber" , "Indian yogurt dip" , "Indian side-dish of cucumber and yoghurt" , "fare from India" .)
