Step 1

For the Steaks: Pat steaks dry with paper towels. Place one steak in a resealable plastic bag. Using a meat pounder, rolling pin, or small skillet, pound steak out to an even 1/8- to 1/4-inch thickness. Repeat with remaining 3 steaks. Season steaks with salt.

Step 2

Place cornstarch in a shallow dish. Whisk together egg and 2/3 cup buttermilk in a separate shallow dish. Whisk together flour, 2 teaspoons salt, paprika, black pepper, onion powder, garlic powder, baking powder, and cayenne pepper in a third shallow dish. Drizzle remaining 1/3 cup of buttermilk into seasoned flour and rub with fingertips until mixture is coarse like wet sand.

Step 3

Working 1 steak at a time, coat well in cornstarch. Lift steak, shake off excess cornstarch, then transfer to egg mixture. Coat steak well in egg mixture, lift steak, letting excess egg drain off, then transfer to seasoned buttermilk-flour mixture. Coat steak well, pressing seasoned flour all over to help it adhere to the meat. Lift steak, shake off excess flour, and transfer to a wire rack. Repeat with remaining steaks. Let steaks stand for 10 minutes.

Step 4

Place oil in a large Dutch oven or wok and heat to 375°F over high heat. Carefully lift 1 steak and gently slide into oil. Cook, flipping occasionally, until golden brown and crisp on both sides, 2 to 4 minutes total. Transfer steak to a paper towel-lined tray and season with salt to taste. Repeat with remaining 3 steaks.

Step 5

For the gravy: Transfer 1/4 cup of hot frying oil to a medium saucepan placed over medium high heat. Add flour and whisk constantly until mixture turns light brown, about 1 minute. Slowly whisk in milk. Stir in pepper and bring to a boil. Reduce to a simmer and cook, stirring occasionally, until slightly thickened, about 4 minutes. Remove from heat; season with salt and additional pepper to taste.

Step 6

Transfer steaks to plates, top with gravy, and serve immediately.
