Salt and Vinegar Potato Salad

Ingredients

1 large red onion, cut lengthwise into 1/3-inch-wide wedges and layers separated
1/2 cup plus 2 tablespoons cider vinegar
2 teaspoons salt
5 lb medium yellow-fleshed potatoes such as Yukon Gold
2 to 2 1/2 teaspoons Old Bay seasoning
1 1/4 teaspoons sugar
3/4 cup extra-virgin olive oil

Directions

Toss together onion, 2 tablespoons vinegar, and 1/2 teaspoon salt in a bowl. Marinate at room temperature, tossing occasionally, until slightly softened and pink, about 45 minutes.

Cover potatoes with salted cold water in a 5- to 6-quart pot, then simmer, uncovered, until just tender, 15 to 20 minutes. 3While potatoes cook, whisk together 2 teaspoons Old Bay seasoning with sugar, remaining 1 1/2 teaspoons salt, and remaining 1/2 cup vinegar in a small bowl.

Drain potatoes in a colander, and when cool enough to handle but still warm, peel and cut into 1/2-inch-wide wedges. Toss warm potatoes with vinegar mixture in a large bowl. Add onion mixture and oil, tossing to combine. Add more Old Bay seasoning (to taste) if desired. Serve warm or at room temperature.
