Are ranch and buttermilk the same thing?

Ranch and buttermilk are not the same thing. Buttermilk is a fermented dairy drink made from the liquid left after churning cream into butter. It is slightly sour and has a tangy flavor. Ranch dressing, on the other hand, is a creamy salad dressing made from a combination of mayonnaise, buttermilk, sour cream, herbs, and spices. It is typically used as a dip or dressing for vegetables, salads, and other foods.
