Seiyu's "On the Gohan Hot and Sour Soup with Black Vinegar" is an authentic Asian menu just by pouring it over rice! The mild starchy sauce goes well with the rice.
I actually purchased and tried "On the Gohan: Hot and sour soup with black vinegar" from Seiyu, which is sold by Seiyu. Just by pouring it over rice, you can create an authentic Asian menu.
