Pepper restricted by winter's perseverance (11)
I believe the answer is:
intersperse
'pepper' is the definition.
'restricted by winter's perseverance' is the wordplay.
'restricted by' says the answer is hidden in the clue.
'INTERSPERSE' can be found hidden inside 'winters perseverance'.
(Other definitions for intersperse that I've seen before include "Dot" , "Spread throughout" , "Scatter - enterprises (anag)" , "Scatter between other things" .)
