Clean the chicken and season with 2 tbsp of all-purpose seasoning.
Mix the flour, cornstarch and remaining all-purpose seasoning in a large bowl.
Whisk egg whites in another bowl.
Dredge each piece of chicken by dipping it in the egg then in the flour mixture.
Heat the oil to 350°F in a large dutch pot.
Fry chicken pieces until golden brown. Rotate using tongs to make sure each side is browned. Do this in batches so you don’t overcrowd the pot and lower the temperature of the oil.
Sprinkle each piece of chicken with salt as it comes out of the oil.
Place the chicken on a sheet pan lined with parchment paper and bake until the chicken has reached an internal temperature of 165°F.
