Peel and wash the potatoes and slice them into thin slices. Fry bacon and potatoes in a large pan (with lid) in hot clarified butter for about 5 minutes. Season with salt and pepper. Meanwhile peel and chop the onion, add it and fry it for about 5 minutes more.
Whisk the eggs, season with salt and pepper and pour over the potatoes. First let it stand with lid for about 7 minutes, then fry it open for about 3 minutes. Just before the mixture sticks, fold one half over the other with a spatula. Wash the chives, shake them dry, cut them into fine rolls and sprinkle them on top. Gherkins taste good with it.
