How to Cook Japanese Rice:

Cooking Japanese Short Grain Rice takes a little strategy so it turns out perfectly fluffy and sticky enough to hold your sushi, nigiri, and so on. But don't get too stressed, because its so much easier than you think!

  1. Cover the pot with a lid, leaving a small gap, and bring to a boil over medium heat.
  2. Once the water is boiling, turn the heat to LOW to cook 12-13 minutes.
  3. When it’s done cooking, open the lid and check quickly if the water is completely absorbed. If there’s still water, let it cook a little longer.
  4. Remove from the stovetop to steam with lid ON for 10 more minutes.
  5. Uncover the lid and fluff the rice with a fork or rice paddle. Let cool enough to handle (but still warm!).
  6. (Optional) Stir in the rice vinegar and furikake.

Can you Prep Japanese Rice in Advance?

You can prep Japanese rice in advance by keeping covered at room temperature for up to 6 hours before eating. If your refrigerate the rice, it could become gummy so it's best to prepare your sushi/onigiri same day.

How to Make Onigiri:

  1. Place a bowl full of cold water nearby if you are shaping the onigiri by hand. Wet both the palms of your hands to keep the rice from sticking, then sprinkle a little salt and rub inbetween the palms.
  2. Scoop a handle of slightly cooled but still hot rice into one palm, flatten out, then spoon a little of the spicy tuna. Add some more rice to cover your filling completely.
  3. Dipping your fingers in the water as needed, shape the rice into a triangle-like shape until firm but still light and airy inside. Flatten the edges with your palms to help evenly cook later.
  4. TIP: You can also use saran wrap to help with the molding process!
  5. (Optional) Cooking the Onigirl: Add a little olive oil to a skillet over medium high heat. Cook the onigirl for 2-3 minutes on each side, until golden.
  6. Serving the Onigiri: Toast the nori sheets over an open flame for 30 seconds, then cut into small rectangle to fit the bottoms of your onigiri. Wrap a strip on one side of the onigiri and fold over to help stick. You can also roll the edges of the onigiri in furikake, if desired. Enjoy!

TIPS for Making Homemade Onigiri:

  1. Wet your hands. It's easiest to mess with the rice with wet hands so it doesn't stick to your hands.
  2. Salt your hands. If you are molding the onigiri by hand, I suggest running your hands under cold water, thens sprinkle a little slat in your palms to helps coat the rice as your form it. It will also help the onigiri stay fresher longer!!
  3. Use a Mold (if possible). Silicone molds found on Amazon or at larger retailers (like Target) will help make things a lot easier in keeping the onigiri from breaking apart in your hands. You can also add a pinch of salt over the outsides of the rice to keep it fresher longer.
  4. Invest in a rice cooker. If you plan on making lots of homemade sushi, sushi bowls, onigiri, or just a huge rice lover (as me and my family are!) then a rice cooker will save you LOTS of preparation/cooking time! This is one of my favorites from Amazon.

How to Store Onigiri?

Onigiri should be covered with plastic wrap or sealed tightly in an airtight container in the fridge up to 2 days.
