With stone you'll almost always get it in the first couple of uses as you grind the rough edges down to a "smooth" surface. I just do a couple of "dry runs" in a new mortar with some cheap salt/pepper to get it smooth before using it properly. You can get ceramic which shouldn't have this issue, but they seem to only be smaller sizes.احصل على السعر
