JAPANESE FOODS

31.01.2023

As the cold winter weather creeps in, don’t we all want to eat something simple and comforting, something that reminds us of the warmth of our homes? I am here to introduce Tonjiru. Tonjiru (or Butajiru) is a broth of stewed vegetables and pork, seasoned with miso. Common ingredients in Tonjiru include pork (usually pork belly or other fatty cuts), burdock, konjac, and earthy root vegetables like carrot and daikon radish, seasoned with dashi and miso. It is the perfect winter dish to make your insides feel warm.

History

Tonjiru is a dish often served at ski resorts and during the winter months in Japan. A special characteristic of this soulful soup is how the fat in the pork creates a layer that rests on the surface of the broth, keeping it warm for a longer time. Its simplicity and taste make this dish so popular with so many people, but theories of the origin of this dish are varied. Let’s take a look at some:

The theory of 薩摩汁 (Satsuma-jiru)

The first theory is that a similar dish from Satsuma Prefecture was the prototype for Tojiru. Foreign influences in the Meiji Period were the trigger of widespread meat consumption in Japan. However, prior to this, the Satsuma region already had a custom of eating meats like pork and chicken accompanied by miso soup. This was known as Satsuma-jiru. As the Meiji government promoted meat consumption to the broader Japanese population as a means of improving physique, variations of Satsuma-jiru were born that combined local vegetables and konjac. Eventually, the umbrella term for this dish was coined: Tonjiru. 

The theory of 屯田兵 (Tondenhei)

Another theory is 屯田兵 (Tondenhei). The Tondenhei were a group of soldiers that guarded the borders of Hokkaido during the Meiji period. It is theorised that these soldiers invented Tonjiru to keep warm on long nights camping.

The theory of けんちん汁 (Kenchin-jiru)

Kenchin-jiru is very similar to Tonjiru, however, it misses one key ingredient: the meat! Since Kenchin-jiru is a Buddhist dish, meat is omitted. Even the dashi used in the broth is made using kelp and shiitake mushrooms instead of fish. 

 Making Tonjiru

Although Tonjiru can be consumed in many ways, ranging from restaurant side dishes to instant cups, it’s such a homely food that surely homemade is the best. The beauty of a simple dish like this is being able to make it yourself, just the way you like it. No two Tonjiru will taste the same. So, if you have made Tonjiru many times, or have never made it before, this is your sign to try making Tonjiru!
