Instant Pot Sushi Rice

1 . Stage

Place rice in the insert of a multi-functional pressure cooker (such as Instant Pot). Add enough water to cover and rinse rice, mixing it in a circular motion. Strain through a sieve. Repeat until water comes out clear, about five rinses total. Spread drained rice onto a clean cloth and let dry for 10 to 15 minutes.

2 . Stage

Clean kombu gently with a damp towel, but do not remove the white powder, which is important for the umami flavor. Break off a small piece of kombu and place into a small saucepan.

3 . Stage

Place remaining kombu into the Instant Pot with rice and 1 1/4 cups water. Close and lock the lid. Select high pressure according to manufacturer's instructions; set the timer for 2 minutes. Allow 10 to 15 minutes for pressure to build.

4 . Stage

Release pressure on the Instant Pot using the natural-release method according to manufacturer's instructions, about 8 minutes. Release any additional pressure carefully using the quick-release method. Unlock and remove the lid.

5 . Stage

While the pressure is releasing, add rice wine, hon mirin, sugar, and sea salt to the saucepan. Heat over low heat until sugar and salt have dissolved; do not boil.

6 . Stage

Use a rice paddle to gently scrape rice into a glass or ceramic bowl; remove and discard kombu.

7 . Stage

Remove and discard the smaller kombu piece from the vinegar mixture. Sprinkle vinegar mixture over rice and cut it in with the rice paddle. Stir until vinegar mixture is well incorporated and no lumps of rice remain. Allow to cool to room temperature, fanning the rice with a piece of cardboard if desired to speed up cooling.
