Spicy food this person thrice added to bran (7)
I believe the answer is:
biriani
'spicy food this person thrice added to bran' is the definition.
The definition suggests a singular noun which matches the answer.
'spicy food this person' is the wordplay.
I cannot really see how this works, but
'food' could be 'b' (B is an example) and 'b' is found within the answer.
'this person' could be 'i' (the person writing) and 'i' is found within the answer.
This explanation may well be incorrect...
(Other definitions for biriani that I've seen before include "Spicy Indian dish" , "spicy rice dish" .)
