Beat the eggs in a bowl, and place the flour in another bowl. Dip chicken wings into the egg, then into the flour to lightly coat, shaking off the excess.
Melt the margarine in a large skillet over medium high heat.
Pan fry the chicken wings until well browned on all sides, about 10 minutes.
Meanwhile, gently boil the cider vinegar, soy sauce, water, brown sugar, monosodium glutamate, salt, serrano chile peppers, and ginger in a saucepan over medium heat until thickened, 5 to 7 minutes.
Toss the browned chicken wings in the sauce to coat, then transfer the wings to large baking dish with a slotted spoon. Reserve remaining sauce.
Bake in the preheated oven until the chicken is no longer pink in the center, about 30 minutes, rotating and basting with the reserved sauce after 15 minutes.
Sprinkle sesame seeds on the chicken wings before serving.
