Cut off a small portion of both the top and bottom of the green tomatoes, so the cornmeal will adhere to the moist areas.
Cut unpeeled tomatoes into ½ inch slices.
Pour oil to about ½” in a large cast-iron skillet; heat to 375°F.
Beat one egg in a shallow bowl
Add buttermilk and spices to the beaten egg
Put cornmeal in a shallow bowl
Combine ¼ cup cornmeal, 1 tsp salt, pepper, and spices in a shallow bowl.
Dredge the tomato slices in the egg mixture, then in the cornmeal, cover both sides.
Drop tomatoes, in batches, into hot oil, and cook for 2 minutes on each side or until golden.
Repeat when you turn the tomatoes over.
Drain on paper towels or a rack. Sprinkle tomatoes with salt.
