About this dish

Iburigakko is an Akita preserve made by hanging whole daikon in hardwood smoke for several days, then maturing it for about two months in a bed of rice bran, steamed broken rice, salt, sugar, and turmeric.

Smoking removes moisture and gives the radish an amber surface, while the cool winter fermentation develops its firm texture and savory flavor. This is a large traditional batch that requires a dedicated outdoor smoker, a sanitized food-safe vessel, and careful packing so every radish remains in contact with the pickling mixture.

Instructions

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

6 steps
  1. 1
    Prep

    Remove soil and root hairs from 12kg whole daikon and wash thoroughly in cold water.

    Do not use bruised or soft radishes for long preservation.

  2. 2
    Step

    Tie the radishes in groups of about 10 and hang them in a dedicated outdoor smokehouse.

    Maintain steady smoke from oak, cherry, or another hardwood for 4 to 5 days. Never do this in an enclosed indoor space because of fire and carbon monoxide hazards.

  3. 3
    Finish

    Finish smoking when the surface is evenly amber and the radishes have lost enough moisture to bend.

    Rinse soot and dust off quickly with cold water and dry with a clean cloth.

  4. 4
    Season

    Mix 1.5kg steamed broken rice, 1.5kg rice bran, 1.5kg salt, 1kg coarse sugar, and 5g turmeric evenly to make the pickling bed.

  5. 5
    Control

    Spread a thin layer of mixture in a sanitized, fully dried food-safe vessel.

    Pack one tight layer of smoked radish, cover with mixture, and repeat. Bury the top completely, then add a clean drop lid and weight.

  6. 6
    Finish

    Mature for 50 to 60 days in a cool, dark winter location.

    Rinse the rice bran quickly from a finished radish and slice thinly. Discard the batch if mold, offensive odor, or abnormal slime develops.
