This creamy, tangy potato salad is a nostalgic American BBQ side dish. Red potatoes soak up red wine vinegar while warm, then get folded with eggs, celery, red onion, sweet gherkins, mayonnaise, Dijon, and parsley for the perfect cookout bowl.
For the best flavor, don’t skip seasoning the warm potatoes with vinegar, salt, and pepper. Make ahead: prepare up to 1 day in advance; stir and refresh with a spoonful of mayo or a splash of vinegar before serving. Stir in 1–2 tbsp pickle brine for extra tang, if desired.
