Grown-Up Oyster Gratin

Grown-Up Oyster Gratin

An oyster gratin with a grown-up flavor, balancing richness and freshness with white wine and white miso. Oysters for cooking, carefully washed with potato starch, and leeks slowly seared to draw out their sweetness, are folded into a rich miso-style white sauce made with equal parts milk and heavy cream, then topped with several kinds of cheese and baked in the oven. A finish of coarsely ground black pepper tightens up the flavor.

INSTRUCTIONS

Instructions

  1. 1

    Transfer the oysters for cooking to a bowl and sprinkle with potato starch. It will be powdery and hard to mix, so add a little water and mix gently so the oysters do not break apart, washing the frilly edges thoroughly to remove grit.

    0:23~5 min
  2. 2

    Once the mixture turns dark, rinse with water. Change the water several times and rinse about 4-5 times until the water runs clear.

    1:11~3 min
  3. 3

    If left wet after washing, the dish will turn watery, so pat the oysters thoroughly dry with paper towels.

    1:36~2 min
  4. 4

    Dust the oysters with 2 tablespoons of flour and mix gently to coat.

    1:42~2 min
  5. 5

    Cut the leek into 3-4 cm lengths. That completes the prep.

    2:32~3 min
  6. 6

    Add olive oil to a frying pan and spread the leek and oysters evenly so the pieces do not touch each other. Leave them undisturbed over medium heat for a while to slowly develop a sear and draw out the sweetness of the leek.

    3:01~8 min
  7. 7

    Once nicely browned, add 80 cc of white wine. Raise the heat to cook off the alcohol.

    3:48~3 min
  8. 8

    Once the alcohol has cooked off, add 3 tablespoons of white miso and dissolve it thoroughly so no lumps remain.

    4:04~2 min
  9. 9

    Add 100 cc of milk and 100 cc of heavy cream to make the white sauce. Simmer for a while, and once it thickens, taste and adjust the seasoning with salt.

    4:29~8 min
  10. 10

    Transfer the finished sauce to a heatproof gratin dish and top with as much grated cheese and Grana Padano as you like.

    5:15~2 min
  11. 11

    Bake in an oven preheated to 230°C for about 15 minutes to brown the top. A toaster oven also works.

    5:36~15 min
  12. 12

    Finish by grinding coarse black pepper over the top and it is done.

    6:01~1 min
