Classic Potato Salad
 
4 pounds russet potatoes (about 8 medium)
Coarse salt
3 tablespoons cider vinegar
3 large eggs
1 cup mayonnaise
½ teaspoon celery seeds
1 teaspoon dry mustard powder
½ teaspoon freshly ground pepper
3 celery stalks, cut into 1/4-inch dice
1 small onion, cut into 1/4-inch dice
10 cornichons, cut into 1/4-inch dice
3 scallions, trimmed and thinly sliced
2 tablespoons coarsely chopped fresh flat-leaf parsley
1 teaspoon sweet paprika
 
1. In a large saucepan, cover potatoes with water by several inches. Bring to a boil, then add 1 tablespoon salt. Reduce heat and gently boil until potatoes are tender when pierced with the tip of a sharp knife, about 25 minutes. Drain. Peel potatoes while still hot, using paper towels to protect hands; cut into 1-inch pieces. Transfer potatoes to a bowl and drizzle with vinegar; let cool.
 
2. Place eggs in a small saucepan; fill with enough cold water to cover by 1 inch. Bring to a boil; turn off heat. Cover; let stand 11 minutes. Transfer to a bowl and cover with cold water; let cool and peel. Cut 2 eggs into ¼-inch dice. Slice remaining egg into ¼-inch- thick rounds; reserve for garnish.
 
3. Combine diced eggs, mayonnaise, celery seeds, and dry mustard in a large bowl; season with salt and pepper, and whisk to combine. Stir in potatoes, celery, onion, cornichons, scallions, and parsley. Refrigerate at least 30 minutes or up to 1 day. Just before serving, garnish with paprika and egg rounds.
