Botebotecha

Botebotecha is a tea or maybe better kind of snack, available in Japanese city of Matsue (western Honshu). It is made by mixing together tea flowers and hot tea in a tea bowl using a tea whisk. After that shiitake mushrooms, koyadofu (tofu) and other vegetables are added while the mixture is still hot.
The name Botebotecha comes from "bote-bote" sound that is made by the tea whisk as tea is mixed. Botebotecha used to be a food of poor during famine in the Edo period. Now Botebotecha is served as local delicacy.
It is customary to pat the bottom of the tea bowl as you drink the tea, vegetables and all and without using chopsticks, in one long gulp.
