Trim the tomato cores and slice the tomatoes into 1/4–1/3" thick rounds. Arrange them in a single layer on a rack or paper towels and season liberally with salt on both sides. Let them sweat, then blot any surface moisture before coating. Top Tip: Let the salted tomato slices sweat long enough to draw out moisture — that’s the secret to a crisp crust instead of a soggy one.
4 medium about 1½–1¾ lb green tomatoes, Kosher salt
Whisk eggs with buttermilk in a shallow bowl until smooth and well combined.
2 large eggs, 1/2 cup buttermilk
In another shallow bowl, stir together flour, cornmeal, salt, pepper, and a pinch of cayenne until evenly blended.
1/2 cup all-purpose flour, 1/2 cup yellow cornmeal, 1 teaspoon Kosher salt, 1/2 teaspoon black pepper, 1/8 teaspoon cayenne pepper
Pour oil into a heavy skillet to reach a shallow depth of ½ to ¾ inches deep and heat over medium–medium-high. Use a thermometer to reach a frying temperature of roughly 350°F (175°C)., or test by dropping a pinch of the dry mix - it should sizzle and brown gently without smoking.
1½–2 cups (oil should be roughly ½ to ¾ inch deep in the skillet) vegetable oil
Working in batches, dip each tomato slice in the egg-buttermilk, letting excess drip off, then press into the flour-cornmeal mixture. Carefully place slices in hot oil and fry until golden and crisp, flipping gently with tongs. Keep the oil between 325–350°F. Too hot and the crust browns before the tomato heats through; too cool and it will absorb excess oil. Adjust heat as needed between batches.
Transfer fried tomato slices to a wire rack over a baking sheet or a plate lined with paper towels to drain. Sprinkle with sea salt if desired. For multiple batches, keep finished slices warm on a rack in a low oven to maintain crispness.
Serve with lemon wedges, hot sauce, or a simple remoulade. They’re great on their own as an appetizer or as a crunchy upgrade for a BLT or tailgate sliders.
