01 - Pat the shrimp completely dry with paper towels to ensure proper breading adherence. Season evenly with salt and black pepper.
02 - Arrange three shallow bowls: place cornstarch in the first, beaten eggs in the second, and panko breadcrumbs in the third. Line a baking sheet with parchment paper for coated shrimp.
03 - Dredge each shrimp thoroughly in cornstarch, shaking off excess. Dip into egg wash, allowing excess to drip off, then press into panko breadcrumbs to coat completely. Transfer to prepared baking sheet.
04 - Whisk together mayonnaise, sweet chili sauce, Sriracha, honey, and rice vinegar in a medium bowl until smooth and fully combined. Set aside for tossing.
05 - Pour vegetable oil to a depth of 2 inches in a deep skillet or pot. Heat to 350°F, maintaining temperature throughout frying for optimal crispiness.
06 - Fry breaded shrimp in small batches to avoid overcrowding, 2 to 3 minutes per batch, until golden brown and cooked through. Remove with slotted spoon and drain on paper towel-lined plate.
07 - Transfer fried shrimp to a large bowl. Pour prepared Bang Bang sauce over shrimp and toss gently until each piece is evenly coated.
08 - Arrange coated shrimp on a serving platter. Sprinkle with sliced green onions and toasted sesame seeds. Serve immediately while crispy.
