Pulverised in can, my French spice (8)
I believe the answer is:
cinnamon
'spice' is the definition.
(cinnamon is a kind of spice)
'pulverised in can my french' is the wordplay.
'pulverised' is an anagram indicator.
'my french' becomes 'mon'.
'in'+'can'='incan'
'incan' anagrammed gives 'cinna'.
'cinna'+'mon'='CINNAMON'
(Other definitions for cinnamon that I've seen before include "Spicy bark" , "Spice from dried bark" , "Aromatic tree bark used as a spice" , "'Spice in con man, strangely (8)'" , "Yellowish-brown - spice" .)
