Pastoral salad dressing, also called ranch salad dressing or country salad dressing, is an American salad dressing, usually made from buttermilk, salt, garlic, onion, mustard, herbs and spices mixed with mayonnaise. Sometimes sour cream and yogurt are used to replace buttermilk and mayonnaise in the ingredients. Since it surpassed Italian salad dressing in 1992, Pastoral Salad Dressing has been the best-selling salad dressing in the United States. In the United States, it is also often used as a dipping sauce and seasoning for potato chips and other foods.
