I think Black Hand is right on overcooking the live. Another thing is to pan fry it after you've fried some crumbled bacon in the pan. Fabulous.
One comment on the overcooking thing though. Forty years ago my wife was very anemic. I don't know if they still tout liver as a treatment but she was supposed to eat it every other day. Tha bad part was "Hot Skillet - Flop the Liver in the Skillet for 30 seconds - flip it over for 30 seconds. EAT IT. That's terrible. After getting sick a few times she compromised I think on 2 minutes on each side.
