Cole & Mason's black granite mortar is not only beautiful but also very functional. The mortar is designed to be sturdy and the user gets a good grip on it. Petkel is very wide at the end and convex at the base of the mortar, so it grinds both dry and moist foods efficiently and without spilling. The exterior of the mortar is elegantly polished. Cole & Mason mortars represent the best of their kind and are the dream of the discerning chef!
