I tried strange Ochaduke.
I put a manju ,a bun with bean-jam filling, on rice and soaked Wakocha.
Wakocha is Japanese black tea.
Japanese does not put sweets on rice.
and does not soak with black tea on rice.
Generally, Japanese put spicy food on rice and soak with sencha, houjicha or bancha.
The taste was surprisingly good.
I think that wakocha may match with rice.
