Place the cured pork loin on the fat pan of the oven. Bake in the preheated oven (electric cooker: 200 °C/ gas: level 3) for about 1 hour. In the meantime, boil eggs hard for 10 minutes. Wash potatoes thoroughly and cook in boiling water for 20 minutes. Wash herbs, dab dry, puree with yoghurt and crème fraîche in a mixer and place in a bowl. Quench the eggs, peel and halve them.
Put 1 egg aside. Take out the remaining egg yolk and pass it through a sieve to the yoghurt. Chop the egg whites finely and add to the sauce. Season to taste with salt, pepper and sugar. Cut the rest of the egg into slices, put 2 slices aside for garnishing. Finely chop remaining slices. Drain potatoes, rinse and peel. Keep potatoes warm. Take the slices out of the oven, let them cool down a little and cut them into slices. Arrange potatoes, meat and some sauce on a plate. Sprinkle with chopped egg.
