Intelligent kitchen aid
Milli creates the necessary friction and simultaneously the largest possible contact surface between mortar and pestle so that no material residue sticks. The uneven irregularities (dimples) are concave to the inside. They are large and not very deep. The edges of the dimples are sharply polished which additionally facilitates the friction process. Ceramics are used only on the pestle head and in the core area of the bowl because it is fragile. It is replaced with silicone everywhere else.
