Perfect potato salad

Potato salad is widely believed to have originated in Germany, spreading largely throughout Europe, the United States, and later Asia.[1][2] American potato salad most likely originated from recipes brought to the U.S. by way of German and other European immigrants during the nineteenth century.[2][1]

American-style potato salad is served cold or at room temperature. Ingredients often include mayonnaise or a comparable substitute (such as yogurt or sour cream), herbs, and raw vegetables (such as onion and celery).[3] South German-style potato salad is served warm or at room temperature and is made with a vinaigrette, (rather than a creamy mayonnaise-based dressing), and typically includes bacon.[4] North German potato salad is served cold or at room temperature. It is typically made with mayonnaise, hard-boiled egg and sweet or sour pickles. The American-style potato salad is likely to have originated from this version.[5] Asian-style potato salad is similar to American-style potato salad, but has a sweeter and eggier flavor.
