German-Style Potato Salad

Can't believe this recipe hasn't been reviewed yet! It has been my go-to German Potato Salad recipe for years, always with kudos from family and friends. Last night I served it at an outdoor patio gathering, pairing it with a selection of German-style grilled sausages and grilled fresh peaches, and as usual the potato salad was a solid hit with multiple requests for the recipe. I follow the recipe exactly as printed and have never found the need to modify it. Don't worry that the dressing quantity seems small. The ingredients just seem to meld into perfect balance during the 1-hour rest period before serving. I slice the potatoes using my food processor and a 4 mm slicing blade and add the potatoes to the dressing while still warm from steaming.
