Prepare the Horseradish Cream, and keep warm. Prepare the Tomato Corn Salsa, if not already done, and set aside.
In a small bowl combine the flour with 1 tablespoon Creole Seasoning. In another bowl, combine the masa harina with 1 tablespoon Creole Seasoning. In a third bowl beat the eggs with the milk. Dredge the oysters in the seasoned flour, then the egg, then the seasoned masa harina.
Heat 1/4 cup of the oil in each of 2 skillets over high heat. When the oil is hot, fry the oysters until they're golden brown, for about 1 1/2 minutes on each side. Drain on paper towels and sprinkle with the salt.
To serve, use a spoon to spread about 1/2 cup of the Horseradish Cream on each of 4 dinner plates. Arrange 6 oysters on each plate like the spokes of a wheel, and mound about 1/2 cup of the salsa in the center. Garnish the rim of each plate with a sprinkling of Creole Seasoning.
Makes 4 first-course servings.
