Ground spicy seed (6)
I believe the answer is:
nutmeg
(Other definitions for nutmeg that I've seen before include "Hard aromatic seed" , "Hard seed of tropical tree grated for spice" , "Aromatic seed - met gnu (anag)" , "Asian tree whose aromatic seed is used as spice when grated or ground" , "(In soccer) kick the ball between an opponent's legs" .)
