““SURIBACHI: A grooved ceramic bowl used for grinding seeds, nuts, or tofu. You can substitute a coffee or nut grinder for the seeds, a miniprep for the nuts, and a food processor for the tofu; however, the suribachi is the most satisfying way to grind these and any foods. But do not bother with a small suribachi since the seeds will jump out and make a mess. If you decide to take the plunge, get the biggest one you can find. Sold at Japanese grocery stores, Korin (see Resources), or Amazon. SURIKOGI””
