Type of light soft roll (7)
I believe the answer is:
brioche
'type of light soft roll' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for brioche that I've seen before include "Soft roll sometimes mixed with currants" , "Sponge cake or roll" , "French cake-like bread" , "Idol" , "Soft roll made of light yeast dough" .)
