The ancestor to the Taco Salad, “Tacos in Tacups,” was served with sour cream to dress it. The first published Taco Salad recipes began showing up in books and magazines in the 1960’s and often did not include sour cream. The addition of traditional salad dressings to the Taco Salad likely has its origins as a substitute for the sour cream as a condiment on top. Sour cream can be a divisive ingredient, and a creamy dressing can be substituted to provide a similar textural component.
