Calf's liver is also known as veal liver, and is the most tender liver to use. It is important to soak the liver in a dish of milk prior to cooking to remove impurities. Dredge the liver in seasoned flour and place it in a hot, oiled pan. Simply sear the liver; do not overcook it because it will become tough. Complimentary flavors to liver include bacon and onions. Take the time to try this long-time family favorite.
