Presented me with a package of pork kidney, so they had to cook... Kidney prepared as usual - steeped (the longer the better), changing the water, bring to a boil and drain off the water (2-3 times), cut and remove the veins. Cut into strips and stacked in a baking dish. I added about 50g of chicken broth, but you can just water. Optionally, add ketchup, salt, pepper, add spices to taste.

Cut onion half rings and put on the kidneys. Luke seems very much, but after baking it will settle. You can even add few salt.

Thin slices cut the potatoes and put on a bow. I have, unfortunately, potatoes was very small.

Cover with a layer of sour cream or mayonnaise. Close the form with a lid and put in heated to 180 degrees oven for 60 to 100 minutes.

Surprisingly, the smell in the kitchen is quite decent, nor what the kidneys and does not smell.

Allow to cool a little and eat...
