Unleavened bread originally ideal with tea and a little butter (7)
I believe the answer is:
chapati
'unleavened bread' is the definition.
(type of Indian bread)
'originally ideal with tea and a little butter' is the wordplay.
'originally' suggests taking the first letters.
'with' is a charade indicator (letters next to each other).
'tea' becomes 'cha' (cha is a type of tea).
'and' means one lot of letters go next to another.
'a little butter' becomes 'pat' ('pat' can mean a lump of butter).
The initial letter of 'ideal' is 'i'.
'cha'+'pat'='chapat'
'i' put after 'chapat' is 'CHAPATI'.
(Other definitions for chapati that I've seen before include "Sort of bread" , "What Indian waiter might bring" , "Indian food" , "Unleavened bread of India" , "Unleavened bread of the subcontinent" .)
