Walnut tofu (胡桃豆腐)

A lot of dishes and sweets use walnuts, but did you know there are local dishes that use them too? In the Tohoku region, there’s a special dish called walnut tofu. It lets you taste the natural flavor of walnuts, and the way you eat it is pretty interesting. Let’s find out more about what makes walnut tofu special and how to make it!

What is Walnut Tofu?

Walnut tofu is a bit different from regular tofu. Usually, tofu is made from soybeans, but walnut tofu is made using walnuts and yoshino kuzu to give it a similar soft and smooth texture.

It’s not the only one made this way—there’s also sesame tofu. But let’s focus on walnut tofu. You can find this unique tofu in places like Esashi, Oshu City, Iwate Prefecture, in the Tohoku region. It might sound like a dessert, but it’s actually a vegetarian dish often served at meals and ceremonies instead of fish.

Traditionally, it was shaped like a cylinder, like slices of fish, and served with radishes. People used to eat it with miso sauce because it’s a bit sweet. But now, walnut tofu isn’t just for vegetarians; it’s also enjoyed at tea ceremonies and as a sweet snack, showing how it’s become more versatile over time.

Why Walnut Tofu Wins Hearts in Iwate?

The Unique Charm of Iwate’s Wagurumi Walnuts

Most of the walnuts eaten in Japan come from California or China. But in Iwate Prefecture, they grow a special kind called “Wagurumi.” These Japanese walnuts have a tough shell and are smaller than the ones from other countries. Only about 20% of the nut can be eaten, so they haven’t been sold much until now.

Even though Wagurumi walnuts have less edible part, they have less of the stuff that makes walnuts taste bitter, like tannins and oil. That’s why they’re healthier and easier to eat. People in the area have been enjoying them for a long time, either as they are or by using them to make walnut tofu. Because of these unique qualities, walnut tofu made with these Japanese walnuts is a common and well-loved dish among the locals in Iwate Prefecture.

The Nutritional Powerhouse of Walnuts

Walnuts are a powerhouse of nutrients! They’re packed with omega-3 fats and strong antioxidants like polyphenols and melatonin. Plus, they’re loaded with good fats, vitamins, minerals, proteins, and fiber, and they’re low in sugar and gluten-free, fitting well with modern diets.

Their good fats and fiber help you feel full, making them a great, healthy snack that’s awesome for managing your weight. Among nuts, walnuts stand out for their omega-3s, which help lower bad cholesterol, keep your blood vessels flexible, and boost your brain. Just having an ounce a day covers your omega-3 needs and helps ward off health problems linked to your lifestyle.

History

Walnut tofu has a long history in Esashi, Iwate Prefecture, Japan. It started as a special dish for events like Obon and Buddhist memorial services instead of the usual sashimi. To make it, they fill walnuts with water and sugar, then harden it using scrap flour.

People began liking it a lot, and soon, it wasn’t just for special occasions. It became a part of ceremonies and local get-togethers. People usually eat it with shredded daikon radish and a sauce made from sweet miso, ginger, and sugar.

Making walnut tofu takes more effort than making sesame tofu because they have to remove the skin from the walnuts. These local walnuts, called Onigurumi, have less tannins and oil, making the tofu taste lighter.

In Iwate Prefecture, people really love eating walnuts. They often describe them as having a “delicious taste,” showing how much they’re part of the local food culture. Over time, walnut tofu became more than just a special dish; it became a symbol of the region’s food traditions that have been around for a long time.
