Every country and culture has its own comfort dishes that feel like receiving a hug every time it is eaten, a little taste of home no matter where in the world you are. For Britain, comfort food includes a roast dinner and pie. In Japan, a common comfort food is rice balls.
There are countless varieties of rice balls in Japanese cuisine, which the rest of the world is only now getting acquainted with, thanks to the rise in popularity of making bento boxes.
Two recurring dishes being shared in these bento boxes are onigiri and musubi, which appear to be causing confusion online. So, what are they?
The biggest difference between onigiri and musubi is their name. Onigiri is a word primarily used in the West of Japan and musubi in the East when referring to rice balls. But if you were to order either at a restaurant, you would be presented with the same dish.
What is Onigiri?
Onigiri is a word that has become synonymous with any rice ball online and in Western Japan. However, the actual definition of onigiri is a little more specific.
Made using plain white rice and simply flavoured with salt, onigiri is essentially the Japanese version of a sandwich.
The rice acts as the bread and is moulded around a variety of fillings depending on your personal tastes. These fillings could be vegetable, meat, or fish based but are nearly always savoury and incredibly tasty.
Hence why plain white rice is used, to make it easy to pair any filling you wish with it.
The word onigiri is a take on nigirimeshi which is a type of rice ball entirely covered in nori seaweed. Specifically, a sheet of nori, giving the rice ball a salty finish.
For the most part, onigiri tends to be shaped into a cylinder or triangle as that is easier to do by hand.
But with onigiri trending around the world, various moulds have been developed to create various shapes, from animals to hearts. So long as the filling of the onigiri is covered entirely by the white rice then it can still be considered onigiri.
If you are new to making onigiri, there are a range of simple fillings that you can try. Mixing canned tuna, a little mayo, and soy sauce is one of the easiest options. Or you could use smoked salmon with a little soy sauce.
What is Musubi?
In Eastern Japan, musubi (or o-musubi) tends to be the general word for rice ball. But true musubi is a specific type of rice ball with specific characteristics that sets it apart from other rice ball dishes.
There are a few variations of musubi around the world such as the spam musubi which is a Hawaiian take on the Japanese rice ball.
But at its core, musubi is a white rice ball filled with an array of fillings such as pickled plumbs and salted salmon, but there is really no limit to the things that you can fill a musubi with.
Musubi do tend to be more savoury snacks, filled with ingredients that can pair well with the lightly salted white rice exterior.
You can make your rice ball any shape and still have it fall under the musubi category, so long as the white rice entirely encases the filling and you finish the rice ball off with a strip of nori.
Musubi does not use sushi rice like some would think. Instead, you should use cooked, short grain white rice. You will need to add some extra water to stop the rice from falling apart, but short grain white rice is what is traditionally used.
Similarities Between Onigiri and Musubi
As you may expect from the above, there are far more similarities between onigiri and musubi than differences, such as:
- The Same Dish – Regardless of their differences, onigiri and musubi are one and the same… A rice ball. They can both include an array of fillings without being limited by definition. So long as the fillings are entirely covered by white rice, then the rice ball can be classified as onigiri or musubi.
- Bento Box Favourites – Onigiri and musubi are both heavily featured in bento boxes. They essentially replace what would be a sandwich. The rice and filling are enough to keep you going until your next meal time, which is why they are perfect for bento boxes.
- Cheap And Accessible – The best thing about onigiri and musubi is that they can be as cheap and easy to make as you wish. White rice is extremely accessible and cheap while the unlimited filling means that you can choose to spend mere pennies and still have a wonderful, tasty lunch. More so, musubi and onigiri are extremely easy to make as far as rice balls go.
Differences Between Onigiri and Musubi
In spite of all of the similarities, onigiri and musubi have differences worth noting if you plan to make your own bento box. For example:
- Regional Names – There are several stories behind why various parts of Japan use different names for rice balls. Some think that onigiri was once a word used by the poorer in society, while musubi was reserved for the richer. Regardless of the reason, rice balls are for the most part called onigiri in Western Japan, while musubi is used in Eastern Japan.
- Seaweed Coverage – Onigiri rice balls are traditionally entirely covered by a sheet of seaweed, creating an extra layer of protection and flavour for the rice ball’s filling. On the other hand, musubi rice balls tend to use less, preferring to use a strip of seaweed for decoration rather than a full sheet.
