Mix buttermilk with 1/2 teaspoon of kosher salt in a large bowl.
Add the wings and toss to coat. Refrigerate for 30 minutes.
Heat 3" of oil in a Dutch oven or deep fryer to 350 F.
In a separate bowl, combine the flour, paprika and remaining kosher salt.
Remove the wings from the buttermilk and drain. Do not pat dry.
Place wings in the flour mixture and toss to coat well.
Working in batches if needed, deep fry the wings 8-10 minutes or until they reach 165 F. Transfer to a wire rack over a baking sheet or a paper towel-lined plate to drain.
Transfer the wings to a large bowl.
Combine the hot sauce and Cajun seasoning. Drizzle over the wings and toss gently to coat.
Serve hot.
Notes
You may want to double the sauce recipe. Adjust the Cajun seasoning to taste.
