I'm probably considered a redneck. I eat a lot of stuff other people sniff at. Kidneys are really good either fried or in a stew. Personally, I soak all my meat in reconstituted sweet condensed milk for 1 to 3 days before cooking it.
Of course, I also eat deer liver, squirrel and rabbit liver. And beaver, raccoon, wild pig, ground hogs, etc. Most people can't tell what kind of meat was in a stew as long as you don't tell them.
