Uni Senbei: Classic Japanese Sea Urchin Rice Crackers

Loved by many foodies around the world, the sea urchin roe “Uni (雲丹)” is famous as a delicious sushi ingredient. Uni is not only used in Japanese cuisine, but since the sea urchin has a distinctive natural umami taste, in Japan it is also sometimes used in snack foods.

And when I think of Japanese snacks made with the sea urchin, what comes to mind right away is “Uni Senbei (うにせんべい)”, often abbreviated to “Unisen (うにせん)”, which I purchased this time for the blog article.

Senbei is the most common type of rice crackers in Japan. They are made of non-glutinous “Uruchi” rice and traditionally flavored mainly with soy sauce or salt, but in modern times come in many varieties including Uni Senbei.

Uni Senbei Sea Urchin Flavored Rice Crackers

As the name indicates, Uni Senbei has a flavor of the sea urchin Uni. It is a classic Senbei that has long been loved in Japan. With a nice crispy texture that melts in the mouth, these rice crackers feature the rich umami of sea urchin, and in order to make the most of the original flavor of Uni, these sea urchin Senbei are lightly salted.

Although these Uni Senbei are similar in shape to “Okaki (おかき)” rice crackers, while Senbei are made of non-glutinous rice, Okaki are made from pieces of Mochi or glutinous rice.

Uni Senbei is a casual, common snack food in Japan, so it is available in supermarkets and convenience stores around the country. By the way, I bought this product for about 110 yen (about 1 USD) at a 7 Eleven near my house.
