Crispy chicken like at KFC

1 shallow dish of coarsely crushed unsalted corn flakes (put them in a freezer bag and crush them)
Preparation
For the marinade: place your chicken breasts, cut not too thick, free of fat or small bones, pour all the indicated ingredients on top, mix the chicken with this mixture, film and put in the fridge (2h or more…).
Cooking: Take a piece of chicken out of the marinade, put it in the flour, then in the beaten egg and finally in the cornflakes, pressing a little. Repeat until all ingredients are used up.
You can also cook them in the oven or in a pan with oil.
