Do you have to fry liver first or can slow cook it?

You do not have to fry liver first before slow cooking it. Slow cooking liver is actually a preferred method as it helps to tenderize the meat and prevent it from becoming tough. To slow cook liver, season it with your desired spices and then place it in a slow cooker with some liquid, such as chicken broth or wine. Cook the liver on low for several hours, or until it is cooked through. Once cooked, the liver can be shredded or sliced and served.
