Ingredients

• For the dashi broth

• 60 ml light soy sauce
• 60 ml mirin

• Main ingredients (long simmer)
• 500 g daikon, peeled, cut into 4 cm rounds, pre-boiled in rice-washing water (togi-jiru) until nearly cooked
• 200 g konjac (konnyaku), cut into triangles or rectangles; rubbed with salt and rinsed
• 150 g shirataki, blanched and drained
• 200 g gyū-suji (beef sinew), blanched to remove impurities; threaded on skewers if desired
• Added at 90 minutes remaining
• 4 eggs, hard-boiled and peeled; scored lightly on top to allow broth penetration
• Added at 60–90 minutes remaining
• 150 g hanpen, soft fish cake; cut into triangles

• 150 g gobō-ten, burdock fishcake

Method

1. 1
   Pre-boil the daikon rounds in rice-washing water (togi-jiru) over moderate heat until almost fully cooked through and any bitterness is expelled. Drain and set aside. Blanch the beef sinew briefly in plain boiling water to remove impurities; drain. The daikon is ready when a skewer meets only faint resistance at the centre.
2. 2
   Combine the dashi, light soy sauce, mirin, and salt in a wide, heavy pot. Bring to a gentle simmer over medium heat. Add the pre-boiled daikon, konnyaku, shirataki, and blanched beef sinew. Adjust the heat so the broth holds a steady, quiet simmer — no aggressive bubbling at any point. Simmer for 2 to 4 hours. The broth must never boil hard: boiling clouds the liquid and breaks the delicate ingredients.
3. 3
   This step is where the dish lives or dies. Maintain the temperature at 80 °C — a slow, steady simmer, not a boil — for the full duration. The daikon must become completely soft and transparent, the dashi flavour penetrating to the very centre, while each other ingredient gives its character back into the broth, building a synergistic whole. After 2–4 hours of simmering, the daikon will be translucent throughout and the broth visibly deepened in colour and aroma.
4. 4
   With 90 minutes of cooking time remaining, add the hard-boiled, peeled eggs (scored lightly on top to invite broth penetration). Allow them to absorb colour and flavour through the final simmer. The eggs are ready when their exteriors have taken on the amber tone of the broth.
5. 5
   With 60 to 90 minutes remaining, add the fishcakes — hanpen, chikuwa, gobō-ten — and the age-dashi tofu. Adding them earlier will make them tough; they need only enough time to absorb the broth without losing their texture. They are ready when they have softened and coloured slightly, yielding gently when pressed.
6. 6
   Taste the broth and adjust salt. The broth must be well-seasoned throughout the meal, as it is consumed alongside all the ingredients. Serve the oden directly from the pot, ladling broth over each portion. Note that next-day oden — refrigerated overnight — produces the most deeply penetrated daikon and the most complex broth.
