OzōniJapanese New Year mochi soup

Japanese New Year soup with mochi rice cake in a clear (Kanto) or white-miso (Kansai) broth with vegetables and chicken or fish; the mochi is square and grilled in the east, round and boiled in the west.

Ozōni (Japanese New Year mochi soup)

Origin and history

Zōni is the soup of New Year's morning: mochi offered to the toshigami, the god of the new year, on New Year's Eve is taken down and simmered with vegetables, chicken or seafood. Japan's agriculture ministry lists more than a hundred well-known regional versions. Round mochi was the original form; square cut mochi, easier to make in quantity and carry, spread from Edo, and a line near Sekigahara still divides the square-mochi east from the round-mochi west.

Ingredients

Units
  • 1 l4 1/4 cups water, for the dashi
  • 10 g4-in square kombu (dried kelp)
  • 20 g2 loosely packed cups katsuobushi (dried bonito flakes), or 800 ml (3 1/3 cups) ready dashi and skip step 1
  • 200 g7 oz boneless chicken thigh, excess fat trimmed, cut in bite-size pieces
  • 1 tbsp sake, for the chicken
  • 1/2 small carrot, peeled, sliced 5 mm (1/4 in) thick, cut into plum-blossom shapes if you like
  • 4 small fresh shiitake, stems removed, a cross cut into the caps
  • 1/2 bunch komatsuna (Japanese mustard spinach) or spinach, about 120 g (4 oz)
  • 8 slices kamaboko (fish cake), sliced 5 mm (1/4 in) thick
  • 4-8 kirimochi (square cut rice cakes), one or two per person
  • 1 1/2 tbsp usukuchi (light-coloured) soy sauce
  • 1 tsp mirin
  • salt, to taste
  • mitsuba (Japanese wild parsley) and thin strips of yuzu peel, to garnish; lemon peel can replace yuzu

Method

  1. 1. Make the dashi: soak the kombu in the water for 30 minutes, then heat slowly and lift it out just before the water boils. Add the katsuobushi, bring back to the boil, turn off the heat and let it steep for 2 minutes. Strain through a fine sieve without pressing.

  2. 2. Toss the chicken with the sake and a pinch of salt and leave it for 10 minutes.

  3. 3. Blanch the komatsuna in salted boiling water for 1 minute, cool it in cold water, squeeze it dry and cut it into 3 cm (1 1/4 in) lengths.

  4. 4. Bring the dashi to a simmer in a pot. Add the chicken, carrot and shiitake and simmer gently for 8-10 minutes, skimming off any foam and fat, until the chicken is cooked through and the carrot is tender.

  5. 5. Season with the soy sauce, mirin and a little salt. The broth should be clear, pale and lightly seasoned. Keep it hot.

  6. 6. Grill the mochi under a hot grill, in a toaster oven or on a rack over a gas flame for 6-8 minutes, turning once, until they puff up and turn golden in patches.

  7. 7. Put the grilled mochi in the bowls and arrange the chicken, carrot, shiitake, kamaboko and komatsuna around them.

  8. 8. Ladle the hot broth into the bowls, top with mitsuba and a curl of yuzu peel, and serve straight away while the mochi is soft.

Notes

  • This is the Tokyo (Kanto) style: clear sumashi broth of bonito and kombu dashi, square mochi grilled before going into the bowl.
  • Kansai style, as in Kyoto: white miso dissolved in the dashi, round mochi simmered rather than grilled, and taro, daikon and kintoki carrot all cut in rounds, a shape that stands for harmony.
  • Regional forms run to well over a hundred: chicken broth with a little sugar in Sapporo, sardine dashi in Miyako (Iwate), ungrilled mochi with greens and bonito flakes in Nagoya, flying-fish dashi with yellowtail in Hakata, mochi in sweet azuki soup in San'in. Okinawa traditionally does not eat zōni.
  • Mochi is very sticky: cut it into smaller pieces for children and older people, and eat it slowly.
  • The dashi and toppings can be prepared on New Year's Eve; grill the mochi and assemble the bowls just before eating.

How to read festival information

We work to keep festival information right, but festivals are run by others and details change. Here is how to read what you see on SoupFestivals.

Confirmed or expected

A confirmed date was announced for that edition. An expected date, such as "usually held around mid-October", is an estimate based on past editions, not an announcement.

Places can be approximate

We show a map pin and directions only when the venue's location is verified. If it is still unconfirmed, we keep the known venue name and town without a pin.

Check before you travel

Dates, prices, menus and venues can change, and festivals can be cancelled. Always confirm with the organizer before you go. If their information differs from ours, theirs is the one to follow.

Help us keep it right

If something looks wrong, tell us and we will look at it. Organizers can claim their festival page to send us updates.
