Mix crushed pork rinds and almond flour in a shallow bowl.
Dip chicken thighs in beaten egg, then press into the pork rind mixture, coating thoroughly.
Heat avocado oil in a skillet over medium-high heat. Fry chicken 6–7 minutes per side, until golden and cooked through (165°F internal). Rest on a wire rack.
Whisk together the frying oil or lard, cayenne, brown sugar substitute, garlic powder, and smoked paprika until smooth.
Brush the hot paste generously over the fried chicken while still hot.
