Make the sauce: In a bowl mix together the mayonnaise, Thai chili sauce and sriracha well to combine. Cover and refrigerate for later use.Pro Tip: This recipe is made with a mild amount of spicy/heat taste. If you like less spicy, reduce the sriracha by 1 tsp; if you like more spicy, as a little bit more.
Mix flour, cornstarch, garlic powder, onion powder and first listed salt and pepper. Divide into 2 bowls and set aside
Mix buttermilk and second listed salt and pepper.
In a deep cast iron pot (2.5 qt) heat a full container of vegetable shortening until 300 to 325 degrees.Note: if the oil is too hot, it might crisp/fry the shrimp a bit too quickly and possibly burn. The heat was adjusted between medium/medium low to keep the oil temp around 300 degrees during frying.
While oil is heating, working in batches, lightly toss the shrimp in the first bowl of flour mixture then put it in the buttermilk mixture and let soak for 2-3 minutes.
Remove the shrimp from the buttermilk mixture and toss in the second bowl of flour mixture to coat well before frying.
Place about 5-6 shrimp at a time in the hot oil for about 1-1 ½ minutes to cook. Remove from oil and drain on a paper towel lined plate to remove excess oil.
In a medium bowl, toss some cooked shrimp in sauce mixture
Serve immediately with extra sauce for dipping
Notes
Not a fan of shrimp? This works well with 1 inch chunks of chicken tenders cooking for about 4-5 minutes. The BEST Bang Bang Chicken!
