- 2 cups well-shaken buttermilk
- 2 large eggs
- 1 tablespoon kosher salt
- 1 teaspoon black pepper
- 8 live soft-shelled crabs (preferably 4 to 5 inches wide), cleaned
- About 2 qt vegetable oil
- 1 cup self-rising cake flour
- 1 cup yellow cornmeal
- Accompaniment: cilantro-lime tartar sauce
- Whisk together buttermilk, eggs, salt, and pepper and pour into a 3-quart shallow dish. Add crabs and soak, covered and chilled, 1 hour.
- Heat enough oil to measure 2 inches deep in a wide 4-quart heavy pot (about 4 inches deep) to 375°F.
- Whisk together flour and cornmeal and transfer to a large sealable plastic bag. Lift 1 crab out of buttermilk, letting excess drip off, and shake in bag to coat with flour. Knock off excess flour and transfer to a tray. Repeat with remaining crabs, arranging them in 1 layer as coated.
- Deep-fry crabs, 2 at a time, turning over halfway through frying (watch out for popping), until golden brown, 3 to 5 minutes. Return oil to 375°F between batches. Drain crabs on paper towels and serve with tartar sauce.
