Grinding sesame

These tools-suribachi(すり鉢)& surikogi (すりこぎ)are used to grind sesame seeds.

And I can use ground sesame seeds for a dish like this.20180101_073154_HDR

I bought suribachi (the porcelain bowl) and surikogi (the wooden bar)at 100yen shop.

By the way, “grinding sesame seeds”「ごまをする」 these words also describes a person who sucks up.  Same as “apple polish” or “butter up”.
