Step 1

In a small bowl combine the mayonnaise, sour cream, ketchup, mustard, lemon juice, garlic, horseradish, and Creole seasoning. Stir well to combine. Refrigerate for at least 30 minutes to allow the flavors to develop.

Step 2

Thinly slice the tomatoes, and lightly salt each side. Place in a colander in the sink and allow the salt to draw some of the moisture out for about 10 minutes.

Step 3

In a medium bowl whisk the egg and buttermilk together. In another shallow bowl combine the corn- meal, flour, pepper, and 1/2 teaspoon salt. In a deep skillet or Dutch oven, pour about 1 inch of oil into the bottom. Heat the oil over medium-high heat until the oil reaches about 350°F.

Step 4

Blot the tomatoes with paper towels to remove the excess moisture. Dip the tomatoes in the egg wash, and then dredge them in the cornmeal mixture, pressing lightly to coat them. Fry in the hot oil for 4 to 5 minutes on each side, or until golden brown. Drain on paper towels. Serve with the remoulade sauce.
