6 cups vegetable oil 1 egg 1 cup water 1 cup all-purpose flour 2 1/2 teaspoons salt 1 teaspoon paprika 1 teaspoon onion powder 1/8 teaspoon garlic powder 4 chicken breast fillets 4 sesame seed hamburger buns 4 lettuce leaves 4 tomato slices ***RANCH DRESSING*** 1/3 cup mayonnaise 2 tablespoons sour cream 1 tablespoon buttermilk 1 1/2 teaspoon white vinegar 1 teaspoon sugar 1/4 teaspoon lemon juice 1/8 teaspoon salt 1/8 teaspoon parsley 1/8 teaspoon onion powder 1/8 teaspoon dill weed 1 dash garlic powder 1 dash freshly ground black pepper 2 teaspoons hot water 1/2 teaspoon unflavored gelatin
Preheat 6 to 8 cups of oil in a deep fryer to 350 degrees F.
To prepare the ranch dressing, combine all of the ingredients except the water and gelatin in small bowl. Mix the water with the gelatin in a small cup until all of the gelatin is dissolved. Add this gelatin solution to the other ingredients and stir. Cover and chill the dressing until it's needed.
Beat the egg and then combine it with 1 cup water in a small, shallow bowl. Stir. Combine the flour, salt, onion powder and garlic powder in another shallow bowl.
Pound each of the breast fillets with a mallet until about 1/4-inch thick. Trim each breast fillet until it is round.
Working with one fillet at a time, first coat each fillet with the flour, then dredge it in the egg and water mixture. Coat the chicken once again in the flour and set it aside until all of the fillets have been breaded.
Fry the chicken fillets for 8 to 12 minutes or until light brown and crispy.
As chicken is frying, prepare each sandwich by grilling the face of the hamburger buns on a hot skillet over medium heat. Spread about 1 1/2 teaspoons of the ranch dressing on the face of the top and bottom of the buns. On the bottom bun, stack a leaf of lettuce and a tomato slice.
When the chicken is done frying, remove the fillets from the fryers and drain on paper towels or a rack for a couple of minutes.
Stack one fillet onto the bottom of the sandwich (onto the tomato), then top it off with the top bun. Repeat the stacking process for each of the sandwiches.
