Potato salad is a dish made from boiled potatoes, usually mixed with other ingredients such as mayonnaise, vinegar, mustard, hard-boiled eggs, onions, pickles, celery, or herbs. It is a popular dish in many countries, often served as a side dish, especially during picnics, barbecues, and other social gatherings. The dish is known as salat kartoffel in German, ensalada de patatas in Spanish, and salade de pommes de terre in French. In Hebrew, it is called salat tapatim (סלט תפוחי אדמה). The origins of potato salad can be traced back to 18th-century Europe, where it was initially made with a vinegar-based dressing. Over time, mayonnaise became a popular addition, particularly in the United States, where it is a staple at many family gatherings and holiday meals. Variations of potato salad exist worldwide, reflecting local tastes and available ingredients, such as the use of sour cream in Eastern European versions or the addition of apples in some German recipes.
