Way of cooking from a tin, or do differently (8)
I believe the answer is:
tandoori
'way of cooking' is the definition.
(style of Indian cooking)
'a tin or do differently' is the wordplay.
'differently' indicates anagramming the letters.
'a'+'tin'+'or'+'do'='atinordo'
'atinordo' is an anagram of 'TANDOORI'.
'from' acts as a link.
(Other definitions for tandoori that I've seen before include "Indian cooking in clay oven" , "Indian cooking method" , "Food cooked Indian-style in clay oven" , "Style of Indian cookery" , "dish" .)
