Time to add spice, perhaps ... (6)
I believe the answer is:
season
'spice perhaps' is the definition.
(spicing is a kind of seasoning)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for season that I've seen before include "Add salt, pepper, spice etc" , "Add taste to; part of year" , "' - - of mists ...' (Keats)" , "Add salt, pepper, spices etc" , "Add flavour with salt and pepper" .)
