Genmaicha Yamasaki is a Japanese Sencha style tea, with fire roasted rice. It also goes by it’s pet name, “popcorn tea”.
Legend has it that in the 1400’s, a samurai warlord was being served tea by savant named Genamai. While serving him, she accidentally bumped him and knocked his rice snack into his tea. The rice popped when it hit the hot tea.
The warlord was so enraged that in a fit of rage, he beheaded Genamai on the spot. Turns out, that after the fact he took a sip of his “spoiled” tea and he really enjoyed his accidental beverage.
He named the new concoction Genmaicha Yamasaki, in Genamai’s honour.
