Wash the potatoes the day before and cook them for about 20 minutes. Boil eggs hard, quench, peel and let them cool down. Peel onion and chop finely. Clean, wash and chop the peppers. Dissolve stock in 200 ml hot water.
Mix with vinegar and mustard. Season vigorously with salt and pepper.
Drain the potatoes, peel them and cut them into small cubes (so that the salad holds together better). Pour the broth over them while still hot. Add the paprika and onion. Leave to stand for about 1 hour.
Mix salad cream and yoghurt. Season to taste with salt and pepper. Dice eggs. Cut the gherkins into slices. Wash the chives and cut into small rolls. Grate cheese roughly. Mix everything with the potatoes.
Fill the salad into a springform pan (26 cm Ø) with a tube bottom insert and press well. Cover and leave to cool overnight. Remove from the refrigerator about 1 hour before serving. Turn out onto a large platter just before serving.
