A packet of ranch dressing mix typically yields 1 tablespoon of dry mix when prepared according to the instructions but can vary depending on the brand. The mix is combined with buttermilk and mayonnaise to create a creamy and flavorful dressing. While convenient for quick preparation, it’s important to be mindful of the high sodium and calorie content. Explore alternative options like homemade dressings or vegetable-based dips for healthier choices.
