Making ranch dressing is as simple as combining all of the above ingredients. Let it sit for at least 30 minutes to allow the flavors to come together fully.
Variations: Add the apple cider vinegar if you like a bit more zing. Add the whey if you want to let it sit out for a few hours and lacto-ferment. Add more chives if you want more of an onion flavor. Fresh is best, but you can also use dried herbs if that's all you have: reduce to 1 teaspoon for dried chives and parsley, 1/2 teaspoon garlic powder instead of a fresh clove. Use the sour cream, cream cheese, yogurt, or buttermilk interchangeably, yet know there will be marked differences. Sour cream or buttermilk will be thinner (especially the buttermilk) and have a more basic ranch flavor. Cream cheese will create a thicker "dip" and have a marked cream cheese flavor. Yogurt will be thinner unless you strain some of the whey out and it will impart a more sour flavor.
