The simplest and best way to crush and grind herbs and spices. The ceramic is ttotally sealed so that it will not absorbs flavours or stain, and has a textured surface on the interior of the mortar and the base of the pestle for better crushing and grinding. The mortar has a pouring lip and a contoured bowl and base for ease of handling. Vitrified and non-porous, it will not crack, discolour or take on unwanted flavours.
