First boil the potatoes and let them cool. (I always make jacket potatoes, but boiled potatoes are also possible.) Peel the potatoes and cut into 8 mm thick slices. Then pour the hot meat stock and vinegar over the potatoes. Now mix the sour cream and the chives cut into rolls and add to the bowl. Season the salad with salt and pepper and mix everything carefully.
If you want, you can also add boiled eggs and cucumber. The salad tastes best chilled!
