Simmered Daikon and Konnyaku (大根とこんにゃくの煮物, Daikon to Konnyaku no Nimono)

Simmered Daikon and Konnyaku (大根とこんにゃくの煮物, Daikon to Konnyaku no Nimono)

Created by

Plain home food, and honest because of it: daikon cooked until translucent, konnyaku scored so it drinks the broth, and chikuwa lending quiet sweetness to the pot.

Daikon shows its age quickly. In winter, when it is heavy, crisp, and sweet at its prime, it needs very little from you. Cut it cleanly, soften it first, then let it sit in a good broth until the white flesh turns translucent. That change is the sign to watch for. The radish has stopped being raw vegetable and started becoming the dish.

Konnyaku makes some cooks hesitate. It looks stern, smells a little earthy when you open the package, and behaves like it has no intention of absorbing anything. We persuade it, not by force, but by scoring the surface, blanching it briefly, and simmering it quietly under an otoshibuta, a drop-lid. The cuts give the broth somewhere to enter, the blanching removes the raw smell, and the drop-lid keeps every piece bathing in seasoning without rough stirring.

This is nimono, a simmered dish, one of the core methods of washoku. The method matters more than the menu: dashi, a little soy, mirin, and sake, then time. Chikuwa is not there to shout. It gives a small fish-cake sweetness and makes the pot feel like supper, the way we do it here on a weeknight. Serve it warm, or better, let it cool in its broth and bring it back gently. Simmered food often learns its manners after resting.

Konnyaku has been eaten in Japan since at least the medieval period, made from the corm of the konjac plant and long valued in temple and household cooking for its firm, springy texture. Daikon became one of Japan's most important winter vegetables by the Edo period, when regional varieties were grown for pickling, grating, and simmering. Nimono developed as everyday washoku around the use of dashi and soy-based seasoning, a method suited to stretching small amounts of fish cake or meat through a pot of vegetables.

Equipment Needed

  • Wide heavy pot
  • Wooden drop-lid (otoshibuta), or a circle of parchment with a small center hole
  • Skewer or cake tester for checking the daikon

Instructions

  1. 1

    Shape the daikon

    Peel the daikon and cut it into rounds about 1 inch thick. Shave a thin bevel around the sharp edges, a cut called mentori, so the rounds don't chip and crumble as they simmer. If the daikon is thick, score a shallow cross on one face of each round. That little cut helps heat and seasoning reach the center.

    Choose daikon that feels heavy and has smooth, taut skin. A tired daikon tastes woody, and no amount of soy will make it young again.
  2. 2

    Parboil the daikon

    Put the daikon in a pot and cover it with rice rinsing water, or plain water with a teaspoon of raw rice. Simmer gently for 15 to 20 minutes, until a skewer slides partway in with a little resistance. This first cooking softens the radish and draws out its sharpness, so the finished broth stays clean instead of turnip-bitter. Drain and rinse the rounds carefully.

  3. 3

    Prepare the konnyaku

    Rinse the konnyaku, rub it with a good pinch of salt, and leave it for 5 minutes. Score both faces in a shallow crosshatch, then cut it into bite-size pieces. Blanch the pieces in boiling water for 2 minutes and drain. The salt and blanching remove the packaged smell, while the scoring gives this stubborn fellow more surface to drink from.

    Do not skip the blanching. Konnyaku is clean food, but it carries an earthy scent from its alkaline setting water. Two minutes fixes it.
  4. 4

    Build the broth

    In a wide pot, combine the dashi, soy sauce, usukuchi shoyu if using, mirin, sake, sugar, and salt. Bring it just to a simmer and taste. It should be a little stronger than you want the finished dish to taste, because daikon and konnyaku will soften the seasoning as they cook.

  5. 5

    Simmer quietly

    Lay the daikon rounds in one layer if you can, then tuck the konnyaku and chikuwa around them. Set an otoshibuta, a wooden drop-lid, directly on the food, or use a circle of parchment with a small hole in the center. Simmer gently for 30 to 35 minutes. A hard boil knocks the daikon apart and toughens the chikuwa; a quiet simmer lets the broth move through the pot without bullying it.

  6. 6

    Rest in broth

    Turn off the heat when the daikon is fully tender and translucent at the edges. Let everything rest in the broth for at least 30 minutes, or cool completely if you have time. This is when the seasoning settles in. Rewarm gently before serving, spooning a little broth over the top so each piece shines.

  7. 7

    Plate with space

    Arrange three daikon rounds with pieces of konnyaku and chikuwa tucked between them, building a little height rather than spreading everything flat. Spoon over a small amount of clear broth and finish with yuzu peel or scallion if using. Leave part of the bowl empty. Ma, that open space, keeps plain food from looking heavy.

Chef Tips

  • For meatless cooking, use dashi made from konbu and dried shiitake and omit the chikuwa. That belongs to the temple-kitchen side of the tradition, and it is honmono, not a compromise.
  • A wooden drop-lid, or otoshibuta, is useful because it keeps the broth moving over the food while holding the pieces in place. A parchment circle does the same work at home.
  • If the daikon tastes harsh after parboiling, it was probably not at its best. Keep the dish, but don't hide it with more soy. Serve it as a stronger-flavored side beside rice.
  • This dish is better after resting. Nimono often tastes thin straight from the stove and right an hour later, when the ingredients have had time to drink.

Advance Preparation

  • Make the dashi up to two days ahead and keep it refrigerated. Warm it before adding the seasonings so the sugar dissolves cleanly.
  • The finished nimono keeps for three days refrigerated in its broth. Reheat gently over low heat and do not boil hard.
  • For the best flavor, cook the dish earlier in the day, let it cool in the broth, then rewarm it for supper.
