This is a powdered seasoning blend used to make ranch-style dressing or dip.
To make Ranch Dressing: Combine 1 tablespoon seasoning mix with 1/2 cup mayonnaise and 1/2 cup whole milk. Whisk to combine and refrigerate, covered, 30 minutes. Stir when ready to use.
To make Ranch Dip: Combine 2 tablespoons seasoning mix with 16 ounces sour cream. If time (and for the best flavor) refrigerate, covered, 1 hour before serving. Stir before serving.
A couple of the heavier ingredients tend to drift to the bottom of the container, so shake it well before using.
