Rice, potato, eggplant, onion, and shimeji simmer in ample water before whole sweetfish are laid on top and cooked, allowing the fish to season both broth and vegetables. Rousui is regarded as a local form of the word zosui, meaning rice porridge. This recipe uses 150g rice and 1600ml water so the grains can expand fully. Four cleaned ayu enter only after the vegetables begin softening. Once cooked, their heads, bones, and fins are removed carefully and only the flesh returns to the pot. Nesashi miso, garlic chives, thin sudachi slices, and a little shichimi finish the porridge with salty soybean depth, green aroma, citrus, and gentle heat.

Instructions

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

7 steps
  1. 1
    Prep

    Rinse 150g rice gently until the water is mostly clear and drain for 15 minutes.

    Cut 150g potato into 1.5cm fan-shaped pieces.

  2. 2
    Prep

    Halve 100g eggplant lengthwise and slice 5mm thick; thinly slice 120g onion.

    Trim and separate 100g shimeji, cut 100g chives into 2cm lengths, and slice 1 sudachi into thin rounds.

  3. 3
    Prep

    Scale 4 ayu and inspect the gills and bellies for grit.

    If grit is present, remove the gills and guts and rinse briefly; otherwise leave the bellies intact, wash the surfaces, and dry completely.

  4. 4
    Control

    Put the rice, 1600ml water, potato, eggplant, onion, and shimeji in a wide shallow pot.

    Bring to a boil, stir the bottom once to release the rice, reduce to low, and simmer for 15 minutes.

  5. 5
    Control

    When a chopstick enters the potato halfway, lay the ayu over the vegetables without overlapping.

    Cover and cook over low heat for 10 to 12 minutes, confirming the thickest flesh reaches at least 63°C.

  6. 6
    Finish

    Transfer the ayu carefully to a wide plate and remove heads, backbones, fine bones, and fins, leaving only flesh.

    Dissolve 80g nesashi miso in a ladle of broth, return it to the pot, and stir gently without crushing the rice.

  7. 7
    Control

    Return the ayu flesh with the chives and warm over low heat for 2 minutes.

    Turn off the heat, add the sudachi rounds, divide among 4 bowls, and sprinkle with a share of 1g shichimi.

Tips

Breaking the ayu inside the pot makes fine bones difficult to find. Move the cooked fish to a plate, debone under bright light, and return only the flesh.
Hard boiling after adding miso weakens its aroma and scorches the rice. Warm briefly over low heat and sweep the bottom only once with a spatula.
