Recipe notes
Tips
Variations: You can add vegetables such as diced avocado or finely chopped shallots for added crunch and freshness.
Storage: These onigiri can be stored in an airtight tin for a few hours, but are best kept fresh to prevent the rice from becoming too dry or the nori from softening.
Tip for a more intense taste: Add a little wasabi or chili powder to the tuna sauce for even more zing.
An Ancient Culinary Tradition
Onigiri have been around for centuries. Their origins date back to the Heian period (794-1185), when these rice balls were shaped by hand and eaten while traveling. In those days, they were often wrapped in bamboo leaves or large shiso (Japanese plant) leaves, to protect them and flavour them.
Today, although onigiri are mainly made from plastic film, they remain a symbol of Japanese culinary culture, easy to transport and ideal for a quick, nourishing meal.
Simple Ingredients, Varied Flavors
Onigiri are made mainly from Japanese rice, which is short-grain, sticky and slightly sweet. Once cooked, this rice is seasoned with a small amount of rice vinegar and salt, then shaped into balls or triangles. But the real magic of onigiri lies in the garnish.
Traditionally, the inside of onigiri is stuffed with simple but tasty ingredients, often salty or umami. Here are some popular examples:
Umeboshi: a salted and fermented plum, giving a sour, salty taste.
Spicy tuna: a popular modern version, where the tuna is mixed with Japanese mayonnaise and soy sauce.
Grilled sardines (mentaiko): marinated fish roe, often spicy.
Grilled salmon: a classic of Japanese cuisine, where salmon is lightly salted and grilled before being used as a garnish.
Vegetarian toppings: pickled vegetables or konbu (seaweed) for a lighter version.
Shapes and presentation
Onigiri are traditionally shaped by hand, forming balls or triangles, but they can also take on creative forms to please children or personalize them. Nori, a dried seaweed leaf, is often used to wrap onigiri, offering a crunchy texture and iodized flavor. The nori leaves are usually added just before eating, to prevent them from becoming soft and rubbery.
Onigiri Symbolism
Beyond their simplicity and practicality, onigiri have a strong symbolic value in Japan. They are often associated with moments of conviviality, such as picnics at festivals or meals shared with family. Preparing onigiri by hand is also a gesture filled with affection, often offered with care by loved ones as an expression of love and care.
Onigiri in Popular Culture
Today, onigiri are available in konbini (Japanese convenience stores) all over Japan, offering a variety of flavors from the most traditional to the most modern. They are often seen in films, manga and anime, where they represent not only a practical meal, but also a moment of sharing, often linked to scenes of family or friendship.
A Culinary Experience Easy to Replicate
Easy to prepare at home, onigiri can be adapted to suit your personal tastes. Whether you're a fan of simple flavors or like to experiment with more daring fillings, onigiri allow you to discover an important part of Japanese culinary culture, while creating a convenient and delicious dish to take away.
Onigiri aren't just a meal, they're a part of Japan's history and soul, a perfect example of how simplicity can be sublimated to create something deeply satisfying.
