American-style potato salad is served cold or at room temperature. Ingredients often include mayonnaise or a mayonnaise-like substitute (such as yogurt or sour cream), herbs, and vegetables (such as onion and celery).It is generally considered a side dish, as it usually accompanies the main course. Potato salad is widely believed to have originated in Germany from where it spread widely throughout Europe and later to European colonies.
