This Organic Ranch Dressing mix was born out of a love for ranch dressing, but a consistent lack of buttermilk. Now, yogurt we always seemed to have. This blend will yield roughly ten batches of dressing. To make, combine 1 rounded tablespoon of Organic Ranch Dressing mix with 1 cup of mayonnaise and 1/2 cup of yogurt (OK, if you just can"t shake the traditional, substitute 1/2 cup of buttermilk for the yogurt). Mix well and refrigerate, where it should be good for 1-2 weeks. Each package of our Organic Ranch Dressing contains about 2.2 ounce.
