I boiled the potatoes in their skins. then I let them cool and peeled them. I boiled the eggs, the cheese is grated, I cut the kaizer into cubes, as well as the eggs after I boiled them. I greased a pan with butter and sprinkled with breadcrumbs. I cut the potatoes into slices by placing them next to each other on the bottom of the tray, I added chopped eggs, the cut kaiser and half the amount of cheese, I added salt and pepper, then another layer of potato slices and the other half of the grated cheese. I added salt and pepper. Separately I beat the eggs and mixed with sour cream, salt and pepper and poured over the potatoes. I put it in the oven at the right heat until it browned.
