This was close enough to a wonderful old buttermilk dressing recipe that I didn't need to publish my version. I simply deleted the mayonnaise so the amazing taste of buttermilk shines through. Simple, elegant and especially good served over an avocado and shrimp salad. I''l squeeze a lemon wedge over the salad when ready to serve.
Great blend of seasonings for a basic dressing. I didn't have any instant onion on hand and subbed Penzey's Shallot Pepper Seasoning. I mixed this up one evening and the next used it as the "ranch" base of Avocado Ranch Dressing. It worked perfectly.
