皿 means 'dish'

In Japanese cuisine, beautiful presentations are paramount, beginning with the pottery. Essay 1650 explains the philosophy of such aesthetics, including the Zen idea that the transformation of clay into teacups is a religion itself. The other three essays provide vocabulary that distinguishes between vessels (dishes, bowls, and cups) of different sizes and depths. Those essays explore the terms donburi, hibachi (not what you might think!), suribachi, and hachimaki. Moreover, those sources show how, from a kanji perspective, the crowns of our heads are upside-down pots or flat dishes, also explaining how one might eat a "big serving of the head"!
