A condiment to sprinkle liberally (6)
I believe the answer is:
pepper
I believe this clue is a double definition.
'a condiment' is the first definition.
(I've seen this in another clue)
'sprinkle liberally' is the second definition.
(I've seen this before)
'to' acts as a link.
(Other definitions for pepper that I've seen before include "It's fiery" , "Hot-tasting spice" , "... which can make one sneeze ..." , "Condiment - discharge shot liberally" , "Riddle" .)
