Röd och vit potatissallad med picklad lök

👩‍🍳 Gör så här

1. 1
   Put the potatoes in a pan of cold salted water and bring to the boil. Simmer for 15 mins or until tender and a knife goes in easily. Meanwhile, combine the onion and vinegar in a large bowl, cover and set aside.
2. 2
   Drain the potatoes and return to the pan, then stand for 5 mins to steam-dry. Slice them into bite-sized pieces and add to the bowl with the onion and vinegar, season with salt to taste and toss to combine. Cover and chill until cold.
3. 3
   Combine the soured cream, mayonnaise and mustard, then add to the cold potatoes with the celery, gherkin and dill. Stir with a spatula until well combined, taking care not to break up the potatoes too much. Season to taste, then chill for at least 1 hr before serving.
