Open the oysters, catching the juice.
Detach the oyster by cutting through the adductor muscle, try not to damage them, clean the bottom shell and place the oyster back in it.
Finely chop the shallot and leek. Heat them together with the white wine. Let it reduce completely until all the wine is gone, then add the sour cream.
Mix the cornstarch with the strained juice from the oysters, add it to the preparation. Let it boil briefly.
Then add half of the cheese, taste and season with pepper and salt.
Spread over the oysters, sprinkle the rest of the cheese on top.
Arrange the oysters in a baking dish on a thick bed of coarse salt.
Set your oven to grill mode and let them gratinate for 10 to 15 min at 230°C.
Garnish with fish roe and serve on a decorated platter with coarse salt and pine branches.
