Ingredients
Method
- Cook the potatoes. Cook the potatoes whole with their skins on in boiling salted water for about 20 minutes until fork-tender.
- Sauté the onions. Finely dice the onion. Heat plenty of oil in a pan and sauté until soft, translucent and glassy — not browned. This step is crucial.
- Slice the potatoes. Peel the potatoes while still warm and cut into thin even slices. Place immediately into a large bowl.
- Add the onions. Pour the sautéed onions with all the oil directly over the warm potato slices.
- Make the broth. Using the same pan — do not wash it! — add the water and bring to a boil. Stir in the bouillon powder to make a strong broth. The pan juices from the onions add extra flavor.
- Season the salad. Add mustard, vinegar, salt and pepper to the potatoes and onions.
- Add the broth. Gradually pour the hot broth over the potatoes while gently mixing. Add a little at a time until the salad is moist and well combined.
- Taste and adjust. Add more salt, vinegar or broth as needed.
- Rest. Cover and let the salad rest for at least 1 hour before serving. It tastes even better the next day.
- Finish. Stir in fresh chopped parsley just before serving.
Notes
Always use the same pan for the onions and the broth — this carries all the flavor and is the secret to an authentic Baden Kartoffelsalat. Always cook potatoes with their skins on — they absorb less water and taste better. Slice them while still warm so they soak up the dressing. The onions must be glassy and soft — never browned. Melfor vinegar is the traditional Baden choice — it is lighter and milder than regular vinegar. The salad tastes best after resting for 1 hour — or even better the next day. For a vegetarian version simply use vegetable bouillon instead of beef bouillon.
