If it is fried hard, it is because the oil temperature is too low and the frying time is not mastered properly. You can slice the chicken gizzards into slices and put them directly into the oil pan without adding any seasonings (the oil temperature should be high, When it is almost smoking, add the chicken gizzards), take it out as soon as it changes color, and eat it with a dip in water. It is a good dish to go with wine.
