"In Sweden, Béarnaise sauce underwent a transformation. By the mid-20th century, the sauce became a ubiquitous part of Swedish culinary culture, moving beyond its traditional French roots. Unlike in France, where Béarnaise is often reserved for fine dining, in Sweden, it took on a more casual, everyday role.

Swedish Béarnaise, or Bearnaisesås, adapted to local tastes by emphasizing a smoother, milder flavor profile and often featuring slightly different herb combinations. Pre-packaged versions became extremely popular, found in grocery stores and served at home with everything from steaks and fries to hamburgers and pizza."
