This is how my grandmother made them and I still do today.
wash and drain the chicken livers. Mix an egg with about 3 tablespoons of milk and beat together well. set aside.
Mix together about 1 cup flour, 1/2 tsp of salt,1/4 tsp. black pepper and 1/4 tsp. garlic salt. you can also add seasoned salt and omit the garlic salt. If you like them spicy you can add a a bit of Cheyenne pepper or red pepper flakes. I wouldn't do both at the same time.
Dip the chicken livers in the egg mixture and then coat with the flour mixture. Cook in a fry pan in oil like you would fried chicken until cooked through completely. Be careful not to over cook or they will become to tough and chewy.
