Helen's Asian Kitchen Suribachi Bowl with Wood Pestle and Bamboo Brush is a Japanese-style mortar and pestle. Introduced from southern China in the 11th century, the Japanese mortar (suribachi) and wooden pestle (surikogi) is an important tool in the Japanese kitchen. The literal translation of suribachi is grinding bowl. And that is what it does to perfection. The unglazed ridged interior improves grinding and prevents ingredients from slipping and sliding. The traditional wooden pestle is designed to reduce wear and tear of the ridges. Includes a bamboo brush for dislodging ingredients and cleaning.
