Oriental vessel acceptable to the West (3)
I believe the answer is:
wok
'oriental vessel' is the definition.
(I've seen this in another clue)
'acceptable to the west' is the wordplay.
'acceptable' becomes 'ok' (OK can mean acceptable or fine).
'to' means one lot of letters go next to another (I've seen this in other clues).
'the west' becomes 'W' (abbreviation).
'ok' put after 'w' is 'WOK'.
(Other definitions for wok that I've seen before include "Asian cooking pan" , "Chinese cooking pan" , "Large Chinese frying pan" , "A Chinese large-bowled frying pan" , "Pan used in Chinese cookery" .)
