What differentiates Southern German Kartoffelsalat dressing from the Northern style?

Answer

Southern style uses a warm oil, vinegar, and broth mixture, often served warm

The preparation of Kartoffelsalat (potato salad) serves as a clear marker for regional identity within Germany. In Southern Germany, the salad is frequently dressed using a warm mixture comprising oil, vinegar, and broth, and it is typically consumed while warm or at room temperature. In sharp contrast, the style prevalent in Northern regions tends to adopt a creamier profile by incorporating mayonnaise, which aligns more closely with salad preparations found in neighboring countries.
