Japanese Daikon Oden: The Winter Comfort of Long-Simmered Stew

Ingredients

• For the dashi broth
• 1 piece (10 cm) Kombu, wiped clean with a damp cloth
• 20 g Katsuobushi (dried bonito flakes)
• 60 ml Light soy sauce (usukuchi shoyu)
• 60 ml Mirin
• 60 ml Sake
• For the togijiru pre-cook
• 500 ml Rice-washing water (togijiru), the cloudy water from rinsing uncooked white rice
• 600 g Daikon radish, peeled, cut into 4 cm rounds; a cross scored into one face of each piece
• 200 g Konnyaku, cut into decorative shapes
• 4 pieces Chikuwa (fish cake tubes)
• 2 blocks (about 200 g) Hanpen (white fish cake), cut into halves or quarters; added only in the final 15 minutes
• 4 pouches Mochi kinchaku (rice cake in abura-age pouches), added only in the final 15 minutes
• 4 Eggs, hard-boiled, peeled; added mid-simmer to allow broth absorption
• To serve
• 20 g Karashi (Japanese hot mustard), served on the side for each diner to apply to taste

Method

1. 1
   Prepare the togijiru by rinsing uncooked white rice in cold water and reserving the cloudy liquid. Place the daikon rounds in a saucepan, cover with the togijiru, and bring to a gentle simmer. Cook for 20–25 minutes. The daikon is ready for the next stage when a skewer meets only slight resistance at the centre and the raw bitterness has left the flesh.
2. 2
   Make the dashi. Place the kombu in 1.5 litres of cold water and bring slowly to just below a boil. Remove the kombu. Add the katsuobushi, hold at a bare simmer for 2–3 minutes, then remove from heat and strain. The finished dashi should be pale gold and clean on the nose — a direct, marine depth without murkiness.
3. 3
   Season the dashi with the light soy sauce, mirin, and sake. Taste: the broth should register as quietly savoury — restrained, not assertive — knowing that daikon and konnyaku will release water during the long cook and dilute it further. Correct seasoning conservatively at this stage; final adjustment comes at the end.
4. 4
   Transfer the pre-cooked daikon and the konnyaku to the oden pot. Pour over the seasoned dashi. Bring to a gentle simmer and maintain it without allowing the broth to boil vigorously at any point. This is where the dish lives or dies: a rolling boil will muddy the broth, disintegrate the hanpen when it is added, and toughen the egg; nothing beyond a quiet, trembling surface is permissible for the entire cook. Simmer the daikon and konnyaku for a minimum of 1 hour.
5. 5
   Add the hard-boiled peeled eggs and the chikuwa to the pot. Continue the gentle simmer for a further 30–40 minutes. The eggs are ready when their exteriors have taken on a mocha-brown cast from broth absorption and the whites have firmed to a uniform, lightly tanned surface.
6. 6
   Check the daikon: press a chopstick or skewer through a round with minimal pressure. The daikon must be translucent through to the centre and offer almost no resistance. If it holds firm, continue simmering and test every 15 minutes.
7. 7
   In the final 15 minutes of cooking, add the hanpen and the mochi kinchaku. The hanpen is done when it has swelled slightly and is heated through but still holds its airy, light structure. If simmered too long it will collapse — remove it the moment it is warmed and yielding.
8. 8
   Taste the broth and adjust seasoning with light soy sauce if the long cook has drawn it down. Ladle the broth and an assortment of ingredients into deep bowls. Serve karashi on the side for each diner to apply to taste. The oden is architecturally incomplete without it.
