After countless years of harvesting deer and elk I had never eaten either, others in the party did though. One year, many moons ago my best friend and hunting/shooting companion for 40+ years convinced me to try heart and liver. He marinated the deer I had shot that morning all day in red wine then cooked in a cast iron skillet in bacon grease over very hot coals. Man, it was delicious! Found out what I had been missing all those years. Still haven't tried tongue though. Brains and scrambled eggs are not too bad. I suppose if you get hungry enough almost anything will go down.
