Bread one covered with butter after tea (7)
I believe the answer is:
chapati
'bread' is the definition.
(I know that chapati is a type of unleavened bread)
'one covered with butter after tea' is the wordplay.
'one' becomes 'i' (Roman numeral).
'covered with' is a charade indicator (letters next to each other) (in a down clue, some letters go on top of others).
'butter' becomes 'pat' (a pat can mean a lump of butter).
'after' is a charade indicator (letters next to each other).
'tea' becomes 'cha' (cha is a type of tea).
'pat' after 'cha' is 'chapat'.
'i' put after 'chapat' is 'CHAPATI'.
(Other definitions for chapati that I've seen before include "Indian pancake" , "What Indian waiter might bring" , "Indian food" , "Unleavened bread of the subcontinent" , "Sort of bread" .)
