Time to add salt and pepper? (6)
I believe the answer is:
season
This clue is a double definition.
'time' is the first definition.
(a season is a period of time)
'add salt and pepper?' is the second definition.
(I've seen this before)
'to' is the link.
(Other definitions for season that I've seen before include "instruction in recipe" , "Time of 9" , "Major division of year characterised by weather and growth" , "Salt, maybe" , "Add salt, pepper, spice etc" .)
