Boil the skinned potatoes and the eggs. When the potatoes are soft and the eggs are hard-boile, skin them and remove the egg shells. Then slice them in round-shaped slices.

Put oil in a frying pan and add the breadcrumbs. Fry the breadcrumbs until dark brown. Now the layers are ready.
3.
Butter a heat resistant dish and put some breadcrumbs at the bottom. Then add one layer of round-sliced potato. Then one layer of eggs, and one layer of sour cream. Continue with one layer of breadcrumbs, and add another layer of potatoes, eggs and sour cream. Leave some breadcrumbs and sour cream for the top. Add salt and pepper to each layer depending on your taste.

Put in a preheated oven (200°) and cook for 15 minutes.
