Add salt and pepper (6)
I believe the answer is:
season
'add salt and pepper' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for season that I've seen before include "To dry (wood) for use as timber" , "Major division of year characterised by weather and growth" , "Add flavour at a certain time of year" , "Eg, summer" , "Period of a year" .)
