Brine the chicken: In a large, nonreactive bowl or Ziploc bag combine the chicken, buttermilk, and hot sauce; cover and refrigerate overnight.

Bread the chicken: Sift all breading ingredients 3 times through a gluten free flour tamis (see Note) or very fine mesh strainer into a large bowl, discarding any lumps. Working in batches, remove 4 or 5 tenders at a time from the buttermilk marinade and toss in the breading, coating well. Transfer to a baking sheet and let rest until the breading adheres, 15 to 20 minutes.

Fry the chicken: While the chicken rests, add 2 inches of oil to a large (at least 6-quart) pot and heat to 300°F. Working in batches, fry 4 to 5 tenders at a time until brown and crisp, 5 minutes per batch. Remove to a paper towel to drain. Once all the chicken is fried, season lightly with salt and serve immediately.
