Easy, crispy fried green tomatoes, made with buttermilk and cornmeal ~ serve with rémoulade sauce.
For the remoulade sauce:
1/2 cup mayonnaise, such as Duke’s
2 tablespoons freshly squeezed lemon juice
1 medium scallion, finely chopped (optional)
1 tablespoon finely chopped fresh parsley leaves
1 tablespoon whole-grain or Creole mustard
1/2 teaspoon paprika
1/2 teaspoon hot sauce, such as Louisiana or Tabasco
1/4 teaspoon garlic powder
1/4 teaspoon kosher salt
Pinch cayenne pepper
For the tomatoes:
2/3 cup instant flour, such as Wondra, divided
1 1/2 teaspoons kosher salt
3/4 teaspoon paprika
3/4 cup buttermilk
1 large egg white
1 1/2 teaspoons hot sauce, such as Louisiana or Tabasco
3/4 cup finely ground cornmeal
3 unripe green tomatoes (about 1 1/2 pounds total), cut into 1/4-inch thick slices
1/2 cup canola oil
Make the remoulade sauce. Whisk all of the sauce ingredients together in a small bowl until combined. Cover and refrigerate until ready to serve.
Season the flour. Stir 1/3 cup of the flour, salt, and paprika together in a wide, shallow bowl or pie plate.
Make the wet mixture. Whisk the buttermilk, egg white, and hot sauce together in second wide, shallow bowl.
Prepare the cornmeal. Stir the cornmeal and remaining 1/3 cup flour together in a third wide, shallow bowl.
Bread the tomato slices. Fit a wire rack inside a rimmed baking sheet. Dip each tomato slice in the flour mixture, followed by the buttermilk mixture, and finally the cornmeal mixture.
Set the cornmeal coating. Place the breaded tomato slices on the rack in a single layer. Let sit so the coating sets while the oil heats.
Heat the oil. Heat the oil in a large cast iron skillet over medium-high heat until shimmering, about 5 minutes. The oil should sizzle immediately if you sprinkle flour into it.
Fry the tomatoes. Carefully add 4 to 5 tomato slices and fry until golden-brown, 3 to 5 minutes per side. Transer the fried tomatoes to a paper towel-lined plate.
Fry the remaining tomato slices.
Serve warm the remoulade sauce. Serve the tomatoes immediately with the remoulade sauce.
