Slow down without right to make pastry (4)
I believe the answer is:
bake
'make pastry' is the definition.
(I've seen this in another clue)
'slow down without right' is the wordplay.
'slow down' becomes 'brake' (I've seen this before).
'without' is a deletion indicator.
'right' becomes 'r' (common abbreviation).
'brake' with 'r' taken away is 'BAKE'.
'to' is the link.
(Other definitions for bake that I've seen before include "Cook by dry heat in an oven" , "Cook (bread/cakes)" , "work in kitchen?" , "Oven-cook" , "Cook in a hot oven" .)
