If you are using milk as a coating for chicken, it is recommended to soak the chicken pieces for at least 30 minutes before frying. This will allow the milk to penetrate the chicken and help the flour or breadcrumbs adhere to the chicken more easily.
However, if you have the time, it’s even better to soak the chicken in the milk for a few hours or even overnight in the refrigerator. This will help to tenderize the chicken and make it more flavorful.
When you’re ready to fry the chicken, make sure to drain off any excess milk before coating it in flour or breadcrumbs. This will prevent the coating from becoming too wet and ensure that it sticks to the chicken properly.
