For the dry rub: In a food processor, combine the peppers, garlic, and olive oil, puree until smooth. Season with salt and pepper. For the chicken: Completely coat each piece of the chicken with the dry rub. Place on a baking sheet and allow to sit for 20 minutes. Evenly coat each piece of chicken with the flour. Dip each piece in the egg mixture, removing any excess liquid. Turn back into the flour mixture, coating each side well. Fill a large skillet with oil 2 inches high. When the oil is hot, carefully lay the chicken in the oil, do not over crowd. Fry until golden brown, about 8-10 minutes. Turn the chicken over and continue cooking until done. Season with Essence. Serve with the mustard sauce.
