1. In a large bowl add chicken, pour milk over and refrigerate for one hour.
2. In a large plastic bag with seal, add flour, salt, pepper and sage, mix by shaking. Add chicken coating evenly. Place in refrigerator until needed (can be left overnight or at least an hour, this is truly the secret to a crispy chicken).
3. In a large sauté pan on medium heat pour oil, allow to get hot. Carefully add chicken pieces being careful not to tear into chicken, cover pan. Allow chicken to cook on each side until brown and finished, approximately 10 minutes on each side.
