In a shallow bowl, combine flour, cornstarch, baking powder, salt, and black pepper. In another bowl, place the beaten eggs. In a third bowl, place the panko bread crumbs.

Breading the Shrimp

Dip each shrimp first into the flour mixture, then into the beaten eggs, and finally coat with panko bread crumbs. Press the crumbs onto the shrimp to ensure they stick well.

Heat the Oil

In a large skillet or deep fryer, heat vegetable oil over medium-high heat until it reaches 350°F (175°C).

Fry the Shrimp

Carefully add the breaded shrimp to the hot oil in batches, making sure not to overcrowd the pan. Fry for about 2-3 minutes on each side or until golden brown and crispy.

Drain and Serve

Remove the shrimp from the oil using a slotted spoon and drain on paper towels. Serve hot with lemon wedges and cocktail sauce.
