Step 1

Boil the potatoes in salted water for 15-20 minutes (depending on their size) until soft. Do not over boil. Let them cool down a bit and peel the skins. Slice in thick semi-circles or quarter-circles (again depending on the size of the potatoes). Place the slices in a deep bowl.

Step 2

In a large sauce pan saute the onion in the vegetable oil until soft. Add the vinegar, the vegetable broth and the mustard and stir to combine. Bring to boil and immediately after that pour the hot marinade over the potatoes. Season with salt and pepper.

Step 3

Stir gently, making sure that all slices are coated in marinade and let sit for at least 15-20 minutes. (The potatoes will acquire the landmark creamy coating of Kartoffelsalat and absorb the flavors of the hot marinade).

Step 4

Serve the potato salad as is (taste first to determine if additional seasoning is needed) or fold in other ingredients to customize.
