Ingredients
Method
- Place potatoes in a pot, cover with cold salted water, and boil until fork-tender, 12 to 15 minutes. Drain and let cool slightly.
- In a large bowl, whisk together mayonnaise, sour cream, mustard, vinegar, sugar, salt, pepper, and lemon juice if using. Stir in dill and green onions.
- Add the warm potatoes and celery to the bowl and fold gently until everything is evenly coated.
- Transfer to a serving dish, top with extra dill and pepper, and serve or refrigerate until chilled.
Notes
If you have time, let the salad chill for at least an hour before serving; the dressing tightens and the flavors meld. Stir in a tiny splash of vinegar or a pinch more salt just before serving if it tastes a bit flat after refrigeration.
