Burn entrance of oven (7)
I believe the answer is:
tandoor
'oven' is the definition.
(type of Asian oven)
'burn entrance' is the wordplay.
'burn' becomes 'tan' ('tan' can be a synonym of 'burn').
'entrance' becomes 'door' (door is a kind of entrance).
'tan'+'door'='TANDOOR'
'of' acts as a link.
(Other definitions for tandoor that I've seen before include "It has food cooked" , "Indian oven" , "Clay oven" .)
