Variety of pastry (4)
I believe the answer is:
puff
'variety of pastry' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for puff that I've seen before include "Short burst of wind" , "Advertise" , "Smoke - light pastry" , "Short blow (of smoke)" , "Short gust of wind" .)
