Found this at the Unimart supermarket... Ube Mochi.
This one is manufactured in Taiwan where Mochi, a traditional Japanese rice cake usually served during the Japanese New Year, is available year round.
Like the rice ball, the filling also varies. My favortie ones are from Dezato in New Manila where they have chocolate mochi with dark chocolate filling, green tea filling or the ones covered in crushed walnuts. Enjoy this sweet dessert with hot tea.
