I went and fried up 4lbs of beef heart and 1lb of liver yesterday, mixed together. The spices were simple, just using an onion, some seasoned salt, and pepper. Good stuff. I'm not sure if I'll go for the liver again (funny texture), but the heart is definitely nice. The thing was near perfectly lean too.
Slow cookers aren't allowed in the dorm rooms. I could possibly do it in the floor lounge, but I don't know if it's worth the trouble just yet. There's also the kitchen in the basement, but then it'd be open for anyone to walk past and mess with. Is it likely that someone would? No, but I wouldn't want to risk it.
