A classic German potato salad with a deliciously tangy dressing.
Steps:
1. Boil the potatoes in salted water until tender. Drain and let cool.
2. Prepare the dressing by mixing oil, vinegar, mustard, sugar, salt, and pepper in a bowl.
3. Cut the potatoes into slices and mix with the dressing while still warm.
4. Let the salad sit for at least 30 minutes to allow the flavors to meld. Serve and enjoy!
