A rice paddle or Shamoji is a flat paddle that is made of bamboo, wood, or plastic and is used to stir and serve rice. It is also used to mix sushi vinegar in hot rice when making sushi rice.
It is made out of bamboo and it must be wet lightly before usage, since it is easy for the rice to stick.
Longer versions are available for bigger sushi buckets, however the tip is the same size since the rice should always be handled in small portions when preparing the sushi rice.
The Shamoji was said to have been invented by a monk in Itsukushima, Hiroshima prefecture and has been traditionally passed from generation to generation as a way to symbolize the passing down of family duties.
