In a medium bowl, whisk together mayonnaise, sweet chili sauce, honey and sriracha to make the sauce. Set aside.
In a separate, large bowl, whisk buttermilk, flour, and cornstarch together.
Stir the shrimp into the buttermilk mixture, covering evenly. Set aside.
In a separate bowl, whisk together Panko, garlic powder, onion powder, salt and pepper.
Place the oil into a heavy bottom pan. You want to have about 1 inch of oil in the pan. Turn the heat to medium. If you have a thermometer, you want to get the temperature to about 375 degrees.
When the oil is heating, lightly strain the shrimp, then dredge in the panko mixture, and place in the hot oil. It only takes 1 or 2 minutes per side to be fully cooked. Fry only a few shrimp at a time or the oil temperature will drop and you won’t get a crispy texture.
hen you remove the shrimp from the frying pan, place it briefly on a plate lined with a paper towel to absorb excess oil. Then toss the shrimp with the sauce.
