For the best flavor, use full-fat mayonnaise. Avoid using light or fat-free mayonnaise, as it may result in a less creamy and flavorful ranch. Adjust the amount of Ranch Seasoning Mix to your personal preference. For a bolder ranch flavor, add an extra half-packet of seasoning. This ranch dressing is best enjoyed within 3-5 days, when stored properly in an airtight container in the refrigerator.
