I was cutting up chicken livers today and noticed a kidney looking organ inside the package. Meanwhile I was cooking the chopped livers and didn't notice that there was chopped kidneys already in the pan now. The food smells like piss but I ate it and it tastes fine but, my question is, how do you prepare kidney? Can you just throw it in the pan like liver or do you have to cut it and remove stuff from the inside like some people are saying on the internet? What are the nutritional benefits of Chicken kidneys(I can't find this anywhere)?
I'm pretty sure the giblet was a heart not a kidney. Chicken hearts are about the size of an olive. Their kidneys are much smaller and are usually still on the bird (not in the giblet package). They are too small to cut open and trim like you would do with a beef kidney. Anyway, all these organs are great to eat nutrition-wise.
The nutritional benefits of chicken kidneys specifically are probably pretty nil, since they're so small. However, kidneys in general contain a lot of the B-vitamins and a ton of minerals: http://www.livestrong.com/article/261789-beef-kidney-nutritional-facts/
You can cut off the outer membrane and trim any excess fat, if there is any. As for prep, you can rinse or soak.
My mom makes perfect kidneys (beef that is). She soaks them for at least 3 hours and changes water every hour. Then she simmers them in a small amount of water, adds chopped onions and pickles. Tastes wonderful!
I just killed, de-feathered and gutted my first chook, admittedly a young rooster. I'm a vet nurse and found it all very interesting and different from animal insides. Anyway, I found the kidneys - 2 egg shaped creamy coloured things, about walnut sized (but oval). I don't mind eating offal type things, but hope I'm right in my assumption that these are kidneys.. can anyone confirm? And does anyone have a tasty way to cook these? As chooks don't pee as such, I don't know if they'd taste good or like chook poo! :/ I usually sautee lambs fry (kidney) with bacon, onions and tomato - it's delicious. I coat chicken livers in flour, then quick-fry them in butter (mmm..getting hungry now..) and salt & pepper, then throw over a tossed salad. Chilli or balsamic dressing goes well with this. Maybe I could try doing this with my chicken kidneys... :)
