Eccentric, Dora, into an Indian method of cooking (8)
I believe the answer is:
tandoori
'indian method of cooking' is the definition.
(I've seen this before)
'eccentric dora into' is the wordplay.
'eccentric' is an anagram indicator.
'dora'+'into'='dorainto'
'dorainto' with letters rearranged gives 'TANDOORI'.
'an' acts as a link.
(Other definitions for tandoori that I've seen before include "Type of Indian cooking" , "Clay oven cooking style" , "Indian cooking in clay oven" , "Tornado I found in Indian food" , "Food cooked Indian-style in clay oven" .)
