Cooking Steps

  1. 1

    Make a cross-shaped cut on the dark side of the flounder's skin and wipe off any moisture thoroughly with paper towels. Slice the ginger with the skin on.

    Advice : Making a cut prevents the skin from tearing during cooking and allows the flavors to penetrate better. Wiping off the moisture helps reduce fishy odors.

    Ingredients
    Flounder fillets 3 pieces
    Ginger 15g
  2. 2

    Put water, sake, soy sauce, mirin, and sugar into a frying pan and bring to a boil over medium heat.

    Advice : Boiling the liquid before adding the fish prevents the meat from becoming too tough and helps eliminate fishy smells.

    Ingredients
    Water 200ml
    Sake 100ml
    Soy sauce 45ml
    Mirin 45ml

  3. 3

    Place the flounder in the pan with the cuts facing up, making sure they do not overlap, and place the ginger in the gaps. Cover with a drop lid and simmer over medium-low heat for about 10 minutes.

    Advice : Flounder is delicate and breaks easily, so never flip it! Using a drop lid ensures the liquid circulates and cooks the top side.

    Remove the drop lid and simmer for about another minute while spooning the sauce over the surface of the flounder until the liquid thickens and glazes.

    Advice : When the sauce thickens and looks glossy, it's a sign that it's delicious. Use a spatula to handle the fish gently when plating.
