Ingredient that's specially cut and ground (8)
I believe the answer is:
allspice
'ingredient' is the definition.
(allspice is a kind of ingredient)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for allspice that I've seen before include "Aromatic West Indian tree" , "Aromatic dried fruit of a Caribbean tree" , "fragrant plant" , "Pill case (anag.)" , "Pimento or Jamaica pepper" .)
