What is Onigiri? 

Onigiri or rice ball is a Japanese food or hand-sized snack made from white rice shaped into triangular or cylindrical forms and covered in nori or seaweed.   As a natural preservative, onigiri is traditionally filled with pickled ume, salted salmon, katsuobushi, kombu, tarako, mentaiko, takanazuke, or any other salty or sour ingredient.

Onigiri is a portable, easy-to-eat hand-sized molded rice made using sticky rice and seaweed. There are a variety of fillings that you may place inside onigiri, like tuna, vegetables, and more. 

This triangular food is easy to eat, which makes it a great portable snack. Inside is a delicious mix of fresh fish and vegetables. Nori seaweed wraps around the rice, either partially or fully, to act as a napkin as you eat. 

You can add anything ingredient inside your onigiri that you wish. Generally, the most popular ingredient is a fish of some type like tuna or salmon. Japanese rice balls are also known for being stuffed with delicious fruit filling.  Commonly onigiri has sour plum paste inside as well.

How Do You Make Onigiri? 

Making onigiri is a hands-on process that requires compacting a filling inside freshly steamed rice then wrapping it in dried seaweed. Onigiri is a straightforward dish that can be ready to serve in less than thirty minutes! 

Ingredients required to make onigiri include: 

  • Sushi rice
  • Your choice of stuffing (fresh fish, veggies, fruit, etc.)
  • A bowl of freshwater
  • Salt
  • Nori seaweed wraps
  • Sushi vinegar
  • Furikake
  • Sour plum paste

Working with onigiri can become messy. Have a napkin ready, and be prepared to get your hands dirty. The messiness and general hands-on activity of this process make creating Japanese rice balls is a fantastic family activity. 

Steaming or Boiling Rice

Before making your onigiri, steam your sushi rice. Steaming rice guarantees it forms nicely without becoming sticky. Onigiri requires its rice to form a solid triangular shape. However, it cannot become mushy or sticky when you bite it.

Sushi rice is the best option for making onigiri because of its formability. Creating Japanese rice balls requires manipulatable rice, and sushi rice is a good example of that. This rice takes on shapes nicely.

After boiling your rice, place it in a bowl and mix in furikake. Furikake is a special sushi rice seasoning that provides an assortment of flavors. Primary flavors include vinegar, sugar, and dried bonito flakes. 

Mixing the Stuffing 

There are many possibilities for what people can use as stuffing. Fish and tuna are accurate representations of stuffing. Since these are the most common fillings, many people automatically think of fish when they hear onigiri. However, there are many sweet stuffings too, like strawberry jelly and even chocolate.

The options for the stuffing are endless. Depending on the type of onigiri, the type of stuffing will be different. For instance, breakfast stuffing may contain a nutritious protein to start the day. A snack at lunch might be a sweet, fruity surprise. No matter what, rice balls are a delicious and simple way to celebrate Japanese cuisine.

Mixing the stuffing for your onigiri can be done while you steam your rice if you can multi-task. 

Forming Shape

The triangular shape of the onigiri is an important part of the process because it represents mountains. To guarantee you get a solid form, keep your hands wet while you press your rice together.

Keeping your hands wet might be one of the most important parts of shape forming. Wetting your hands prevent the rice from sticking together as you press it together. When pressing, be cautious with the amount of pressure you give when forming your onigiri. Too much pressure can cause the rice to fall apart.

Stuffing 

Perhaps the most important part of all is the stuffing you put into your Japanese rice balls. The mixture you prepare varies based on preference. Getting the stuffing inside your rice mold is critical. 

When molding your rice balls, make an indent in the rice large enough to hold your stuffing, fill your rice ball, and then fold the rice on top.

Wrapping Onigiri

Not all Japanese rice balls will get wrapped in seaweed. If you choose not to wrap your onigiri, skip this section and move to the serving stage. Otherwise, get your seaweed. 

Seaweed acts as an envelope to seal the components together. The seaweed’s envelope-like role also acts as a plate, perfect for portable eating.

Serving Onigiri

The portable stuffed rice snack, onigiri, does not require utensils or plates to eat. All you need are your own two hands to enjoy this portable rice snack. There are several ways that you may physically serve onigiri. Onigiri goes great with Japanese beer or sake.

The way you wrap seaweed makes a significant impact on how your onigiri comes across. For instance, some people say that traditional triangular-shaped designs with a singular seaweed strip are representative of the gorgeous Japanese mountains like Mount Fuji.

My fascination with Japan began several years back at a roadside bonsai stand while on vacation. I became more interested in the where and why's more than the trees themselves. My love of Bonsai led me to further research my interest in the gardens where they originated from and the places and people that surrounded those little trees. My curiosity was well rewarded upon visiting Saitama where the National Bonsai Museum was located and Omiya Village the bonsai mecca for lovers of this ancient art form. Exploring many towns and villages and even making my way to Japan's furthest southern prefecture of Okinawa. I hope to share my love of this wonderful and exotic place with all those who want to know more about Japan.
