Peel and wash the potatoes and slice them into wafer-thin slices (e.g. with a mandolin or truffle slicer). Place the potato slices in vinegar for about 30 minutes.
In the meantime, preheat the oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer). Line two baking trays with baking paper and brush with oil.
Drain the potato slices and dab them dry well and place them next to each other on the trays. Bake in a hot oven for 20-25 minutes until golden brown and crispy, turning once. Mix approx. 1 tsp salt and 2 tsp paprika.
Pour chips into a bowl. Season while still warm with the paprika salt.
