Method
Step-by-Step
- Scrub the red potatoes, leave the skins on, and cut them into roughly 1-inch pieces. Place them in a large saucepan, cover with cold water by about 1 inch, and salt the water generously.
- Bring the potatoes to a boil, then reduce the heat to a gentle simmer. Cook for 10 to 15 minutes, until fork-tender but still holding their shape.
- Drain the potatoes well and let them cool for about 10 minutes. This leaves them slightly warm, which helps them absorb the dressing without making the mayonnaise mixture greasy or runny.
- Whisk together the mayonnaise, sour cream, Dijon mustard, apple-cider vinegar, kosher salt, and black pepper in a small bowl. Continue whisking until the dressing is smooth and evenly combined.
- Add the potatoes, celery, red onion, fresh dill, and chopped hard-boiled eggs if using to a large bowl. Fold in the dressing gently, taking care not to mash the potatoes.
- Cover the salad and refrigerate for at least 30 minutes, although 1 to 2 hours gives the flavors more time to mingle. Taste before serving and adjust the salt, pepper, or vinegar as needed.
Notes
Start the potatoes in cold, generously salted water and simmer them gently for even cooking. Dress the potatoes while slightly warm, but not hot. Store covered in the refrigerator and serve chilled.
