The purpose of salad dressing depends across cultures. There are many often used salad dressings in North America. Traditional dressings in southern Europe are vinaigrettes, while mayonnaise is predominant in eastern European countries and Russia. In Denmark dressings are often based on crème fraîche. In China, where Western salad is a recent adoption from Western cuisine, the term salad dressing (沙拉酱, "shalajiang") means to mayonnaise or mayonnaise-based dressings.
