Mix the sauce first
Stir mayonnaise, sweet chile sauce, sriracha and lime juice until smooth. Refrigerate while you fry.

Crisp, light-coated shrimp with a creamy sweet-chile sauce — fried hot, drained hard and sauced only at the last second so the crust still cracks.

Stir mayonnaise, sweet chile sauce, sriracha and lime juice until smooth. Refrigerate while you fry.
Pat shrimp dry, toss in buttermilk, then lift and let excess drip off. Mix cornstarch, flour, salt and garlic powder and dredge shrimp thoroughly.
Bring 2 inches of neutral oil to 350°F / 175°C.
Fry shrimp 2 to 3 minutes until pale golden, crisp and just opaque inside. Keep the oil between 340 and 360°F.
Move shrimp to a wire rack for 1 minute. Surface oil and steam are what turn sauce into sogginess.
Transfer hot shrimp to a bowl, add just enough Bang Bang sauce to lightly coat, and toss quickly.
Pile onto a platter, finish with scallions and serve extra sauce on the side.
OPTIONAL UPGRADE
Keep the core recipe clean, or flip this on for one or two high-impact upgrades.
Use these recipe-specific texture cues. Color and curl alone cannot establish safety; use a thermometer to check 145°F / 63°C at the thickest part for cooked shrimp.
The little details that make a big difference.
Do not marinate in the sauce or let coated shrimp sit.
The crust should be crisp and thin, not a heavy batter.
Enough size to stay juicy while the coating crisps.
Oil and steam trapped under sauce erase the texture you just created.
