Red Konnyaku Stew | Comprehensive Explanation of the History, Preparation Method, and Nutritional Value of a Local Dish from Omihachiman, Shiga Prefecture
What is Red Konnyaku Stew?
Red konnyaku stew (akakonyaku-ni) is a traditional stewed dish made with red konnyaku, a specialty product of Shiga Prefecture. Characterized by its vibrant red color, this local dish has been beloved by the people of Shiga Prefecture for many years, prized for its gorgeous appearance and unique elastic texture.
Red konnyaku is also called “Hachiman konnyaku,” and its birthplace is said to be Omihachiman City in Shiga Prefecture. In Omihachiman City, the city buses are nicknamed the “Akakona Bus” and the local mascot character is called “Akakona-kun,” showing how deeply this product is cherished as a representative specialty of the region.
Characteristics of Red Konnyaku
The most notable characteristic of red konnyaku is its vibrant red color. This red hue comes from an iron compound called “ferric oxide,” which maintains its beautiful color even when cooked without fading. Ferric oxide is approved as a food additive and is a safe ingredient that also helps with iron supplementation, making it a health-conscious food material.
Compared to regular konnyaku, red konnyaku has a distinctly stronger elastic texture, and when made into a stew, it absorbs flavors easily. This texture and color have played an important role in Shiga Prefecture’s food culture.
History and Origins of Red Konnyaku Stew
Connection to Oda Nobunaga
There are several theories about the origin of red konnyaku, but the most famous is the one related to Oda Nobunaga. According to legend, when Oda Nobunaga built Azuchi Castle, the flamboyant warlord had red konnyaku created. During the Sengoku period, red was considered an auspicious color among warlords and was used for prayers for victory in battle and celebratory occasions.
Since Nobunaga controlled Ōmi Province, including Omihachiman, and had Azuchi Castle as his base, he is believed to have greatly influenced the food culture of this region. Red konnyaku is thought to have emerged from such historical circumstances.
Connection to Buddhist Culture
Shiga Prefecture is known as an area with many shrines and temples and has long been a devout region. The culture of shojin ryori (Buddhist vegetarian cuisine) is deeply rooted, and konnyaku has been valued as a meat-free dish.
Red is also an important color in Buddhism and is considered an auspicious color used in celebratory events and religious ceremonies. Red konnyaku became connected to this religious background and became established as an essential local dish for special occasions such as festivals, memorial services, and New Year.
Food Culture Rooted in the Community
In eastern Shiga Prefecture, centered on Omihachiman City, red konnyaku is eaten on a daily basis. Today, it is not only made at home but is also incorporated into school lunches, making it familiar to children. It is also widely sold at restaurants and supermarkets, becoming a representative dish of the region’s food culture.
Primary Areas of Transmission
Red konnyaku stew is eaten throughout Shiga Prefecture, but it is particularly actively preserved in the eastern region centered on Omihachiman City. Omihachiman City is said to be the birthplace of red konnyaku, and several konnyaku manufacturers continue to produce it while maintaining traditional methods.
In surrounding areas such as Hikone City, Higashiōmi City, and Hino Town, red konnyaku is a daily staple on dinner tables, and each household passes down its own unique seasoning and cooking methods. In Shiga Prefecture’s food culture research societies and community food education activities, red konnyaku is positioned as an important traditional food ingredient.
Ingredients and Preparation Method for Red Konnyaku Stew
Ingredients (serves 4)
- Red konnyaku: 1 block (approximately 250g)
- Dashi broth: 300ml
- Soy sauce: 2 tablespoons
- Mirin: 2 tablespoons
- Sugar: 1 tablespoon
- Sake: 1 tablespoon
- Bonito flakes: as needed (for garnish)
- Sesame oil: 1 teaspoon (for garnish, optional)
Preparation Steps
- Preparation: Cut the red konnyaku into bite-sized pieces. You can cut it into cubes, julienne strips, or tear it by hand according to preference. Tearing by hand increases the surface area and allows flavors to absorb more easily.
- Blanching: Place the cut red konnyaku in a pot and blanch it in plenty of water for 3 to 5 minutes to remove any bitter taste. Once done, drain it in a colander.
- Dry-frying: Heat a pot over medium heat and dry-fry the drained red konnyaku. Fry until the surface moisture evaporates and you hear a squeaking sound, which helps the flavors absorb better.
- Simmering: Add dashi broth, soy sauce, mirin, sugar, and sake to the dry-fried red konnyaku. Bring to a boil over medium heat, then reduce to low heat and simmer for 15 to 20 minutes.
- Flavor absorption: Reduce the cooking liquid until it is about half its original volume. Gently shake the pot occasionally to ensure the flavors distribute evenly throughout.
- Finishing: Just before removing from heat, add bonito flakes and mix well. If desired, drizzle sesame oil for enhanced aroma.
- Plating: Transfer to a serving dish and garnish with bonito flakes on top to complete.
Cooking Tips
The key to making delicious red konnyaku stew is thorough preliminary preparation. Carefully conducting the dry-frying step removes any unpleasant odor from the konnyaku and allows the seasonings to penetrate better. Additionally, simmering slowly over low heat for an extended period ensures flavors seep thoroughly into the center, resulting in a delicious finished dish.
It tastes good even when cooled, and actually becomes more flavorful when left overnight for the flavors to fully absorb. It is excellent as a make-ahead dish and works perfectly as a bento box side dish.
