Japanese New Year Mochi Soup with White Miso (Zoni)

Zoni is the symbolic soup of the Japanese New Year (Oshogatsu). The mochi (rice cake) signifies resilience and longevity. While Tokyo style uses a clear broth, the Kyoto/Kansai region enriches it with White Miso (Shiro Miso), giving it a sweeter, creamier, and more elegant profile suitable for the holiday table.

Instructions

1

Slice carrot and daikon into rounds. Simmer in Dashi stock with mushrooms until tender (10-15 mins).

Tip: In Japan, carrots are often cut into flower shapes to celebrate the special occasion.
2

Meanwhile, toast the mochi blocks in a toaster oven or dry skillet until they puff up and brown.

Tip: Toasting adds flavor (Maillard reaction) and makes the inside gooey.
3

Remove soup from heat. Dissolve miso in a ladle with some hot broth, then stir back in. Add spinach.

Tip: Never boil miso; high heat destroys its delicate aroma and probiotic qualities.
4

Place toasted mochi in bowls and ladle the hot vegetable soup over it.

Tip: The mochi will immediately soften in the hot broth.

Recipe FAQ
