To make Umeboshi Onigiri, you first need to prepare the nori sheet by cutting it into 3 equal pieces.
Then, make the ume paste by removing the seed and chopping the ume to create a paste.
Collect all the required ingredients. Including salt, a bowl of water, cooked Japanese short-grain rice, nori sheets, and the ume paste.
To assemble the Onigiri, begin by putting the cooked rice into a small bowl and making a small dent in the centre. Add 1 or 2 teaspoons of the ume paste into the dent.
Wet your hands with water. Put some salt (2 fingertips of salt) on your palm, then rub your hands together to distribute the salt.
Take the rice mixture and place it in your hand. Hold the mixture with both hands. Form a round shape (or triangle shape) by pressing it with your fingers and palms. Roll it several times. Repeat this process to create the desired number of Onigiri.
Once the rice has its shape, wrap it in the before-prepared nori sheet. Serve and enjoy your delicious and nutritious Umeboshi Onigiri!
