Stir together mayo, chili garlic sauce, and that optional Sriracha if you're into it. Toss it in the fridge—it keeps fine for two days ahead.
02 -
Let shrimp chill in buttermilk for around 20 minutes so they can soak up all the tenderness.
03 -
Combine salt, pepper, flour, and cornstarch in a mixing bowl. Lay out a cooling rack on a baking sheet for coated shrimp, and get another tray with paper towels ready for draining. Heat up your oven to 200°F so cooked shrimp stay cozy.
04 -
Shake off the buttermilk, and roll shrimp in flour mixture. Knock off the extra flour, then line them up on the cooling rack while heating your oil.
05 -
Pour oil into a deep pot or Dutch oven. Use a thermometer to heat it to 350°F. Medium-high heat works; expect it to take about 20 minutes.
06 -
Fry a few shrimp at once for roughly 4 to 4 1/2 minutes, stirring gently after a minute so they don't stick. Aim for that golden-brown look.
07 -
Transfer fried shrimp to the paper towel setup, then into the warm oven. Fry in batches and make sure the oil is at 350°F before starting the next round.
08 -
Once frying is done, toss shrimp with about a cup of sauce. Save the rest to drizzle over the toppings later.

Build your tacos with a layer of slaw, saucy shrimp, a dollop of extra sauce if you like, and finish with radishes, jalapeños, cilantro, and green onions.
