What significance do potatoes hold in Japan?

Potatoes play an important role in Japanese cuisine and are a popular foodstuff used in many traditional and modern dishes. Potatoes are a staple food, particularly in the northern regions of Japan, such as Hokkaido. Hokkaido is known for its cool climate and fertile soil, which provide ideal conditions for potato cultivation. In fact, around 80% of Japan’s potato production comes from Hokkaido.

Potatoes were first brought to Japan in the 18th century and have since become a staple of Japanese cuisine. They are incredibly versatile and are used in a wide variety of dishes, including soups, stews, salads and side dishes. One of the best-known Japanese dishes featuring potatoes is ‘Niku Jaga’, a hearty stew made with potatoes, beef and onions in a sweet-and-salty soy sauce broth.

In addition to traditional yellow potatoes, sweet potatoes are also very popular in Japan. These can also be used in soy sauce potatoes. Sweet potatoes offer a slightly sweet note and a soft texture that harmonises perfectly with the sweet -salty marinade. They are particularly rich in nutrients and add an interesting flavour variation.

The versatility of the potato makes it an integral part of Japanese cuisine. Whether in hearty stews, as a crispy side dish or in sweet snacks such as Daigaku Jagaimo – potatoes are an indispensable part of Japan’s culinary landscape.

Make your own potatoes in soy sauce: Here’s how

Daigaku Jagaimo is a simple yet impressive dish, which is perfect as a side dish or snack. With just a few ingredients and simple passages, you can conjure up these delicious, crispy potato bites in your own kitchen. Whether you opt for classic potatoes or slightly sweet sweet potatoes, the result will delight you and your guests. Here’s what you’ll need and how to proceed:

  • 500 g potatoes
  • 3 tbsp soy sauce
  • 3 tbsp Mirin
  • 3 tbsp sugar
  • 2 tbsp honey
  • 1 tbsp sesame oil
  • 1 tbsp black sesame seeds
  • 500 ml oil for deep-frying

Wash the potatoes thoroughly and cut them into 2–3 cm pieces. Place the cut potatoes in cold water for about 10 minutes to remove excess starch, then drain and pat them dry.

Make your own sweet potatoes in soy sauce

Heat the oil in a deep fryer or a suitable pan. Fry the sweet potatoes over a medium heat until they are golden brown and cooked through, about 8–10 minutes. Drain the fried sweet potatoes on kitchen paper to remove excess oil.

Tip

The leftover frying oil can be stored and, once cooled, filtered through a fine sieve. This way, you can reuse it in a few days to make this recipe again or prepare another fried dish.

In a separate frying pan or small saucepan, heat the soy sauce, sugar, honey, Mirin and sesame oil over a medium heat until the sugar has completely dissolved and the mixture thickens slightly. Add the fried potatoes to the pan and stir gently until all the pieces are evenly glazed.
