Ingredients
1 1/2 pounds fingerling potatoes, sliced crosswise 1/2-inch-thick (about 4 1/2 cups)
4 large eggs
1/2 cup mayonnaise
1 teaspoon yellow mustard
1 tablespoon white wine vinegar
Pinch of smoked paprika
Coarse salt and freshly ground pepper
1 celery, finely chopped (about 1/2 cup), plus more for serving
3 tablespoons finely chopped red onion, plus more for serving
Preparation
Cover potatoes with water by 1 inch in a medium saucepan and bring to a boil. Cook until tender, about 10 minutes; drain.
Place eggs in a small saucepan; add water to cover by 1 inch. Bring to a rolling boil. Remove pan from heat; cover, and let stand 7 minutes. Drain, and run eggs under cold water to cool.
Peel and halve eggs lengthwise. Remove yolks and transfer to a bowl; mash with a fork. Mix in mayonnaise, mustard, vinegar, paprika, and 2 tablespoons water; press through a sieve. Roughly chop egg whites; add to yolk mixture along with potatoes, celery, and onion. Season with salt and pepper. Toss to combine; top with more celery and onion.
