About this dish

Seigaku mochi is a Chiba rice cake made from ordinary short-grain rice rather than glutinous rice.

The soaked grain is steamed once, rinsed quickly in water to separate every kernel, steamed again until no firm core remains, and pounded. It is associated with the Seigaku teachings and rural reforms of Ohara Yugaku in the Sosa area. Double steaming softens non-glutinous rice enough to bind while keeping the finished cake less sticky than standard mochi. It holds its shape well in soup or a stir-fry and has a soft but clearly grained bite.

Instructions

Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.

5 steps
  1. 1
    Prep

    Wash 1.4kg rice three times until the water is nearly clear and soak in 2L water.

    Soak 4 hours in summer or 8 hours under refrigeration in winter, then drain for 20 minutes.

  2. 2
    Control

    Line a fully steaming steamer with a damp cloth, spread the rice in an even layer, and wrap it.

    Cover and steam over strong, steady steam for 20 minutes.

  3. 3
    Step

    Transfer the hot rice to a large sieve, immerse it in 2L cold water for 20 seconds, and shake quickly by hand to separate every grain. Lift immediately and drain for 5 minutes.

  4. 4
    Step

    Wrap the rice in the cloth again and steam for 10 to 12 minutes.

    Press one grain and confirm it crushes smoothly with no firm white core.

  5. 5
    Step

    Pound the hot rice in a mochi machine for 8 to 10 minutes until no separate grains remain.

    Without a machine, pound in a mortar with a damp pestle to the same state. Divide into 100g portions with wet hands and flatten.
