Blue cheese dressing is a creamy salad dressing made primarily from blue cheese, mayonnaise, and sour cream. It often includes ingredients like buttermilk, vinegar, and various seasonings to enhance its flavor. The distinctive tangy and rich taste of blue cheese gives the dressing its unique character, making it a popular choice for salads and dipping sauces. This dressing is commonly used on salads, particularly those featuring wings or vegetables. It pairs well with a variety of dishes, adding a bold flavor that complements the freshness of greens or the spiciness of fried foods.
