How To Use Onigiri Mould

01.

Dampen the mould with warm water. Ensure you have a small bowl of warm water mixed with a bit of salt close by. Wet fingers will make this so much easier.

02.

Place the Hinoki flat board under the triangle mould.

03.

Add a scoop of rice to the mould and push down with wet fingers until it's filled out the base.

04.

Add a spoon full of your filling (this might take a few turns to get it right. If you add too much the rice won't hold it together).

05.

Add another scoop of rice on top of the filling.

06.

Wet fingers again and push down until the mould is full and flat.

07.

Carefully push the onigiri through the hole so it's resting on the board.

08.

We finished ours off with a wrap of seaweed

10
Press into mould.
