How to cook
Pick out potatoes of the same shape, wash them and boil for 5-10 min. in salted water.
Take them out, scrub them and put for 30 min. in a moderate oven. Use a sharp knife to cut out a cap along the entire length of each potato and dig out the insides with a small spoon. Put salt, black pepper and a little butter inside at the bottom of each.
Break 1 egg into each hollow space and put the potatoes in the oven for 3-4 min. until the egg whites firm up.
Optionally, instead of the butter at the bottom of the potatoes, you can put cottage cheese or crumbled feta.
