Mash the Garlic: Peel and finely mince the garlic. Sprinkle with kosher salt and use a fork or the flat side of a knife to mash it into a paste. This helps it blend evenly into the dressing.
1 clove garlic, ⅛ teaspoon kosher salt
Chop the Herbs: Finely chop parsley, chives, and any optional fresh herbs like dill or oregano. The smaller, the better—this dressing should be creamy, not chunky.
¼ cup chopped flat-leaf parsley, 2 tablespoons chopped fresh chives, 1 to 2 teaspoons chopped fresh dill, 1 teaspoon chopped fresh oregano
Mix the Creamy Base: In a bowl, stir together the mayonnaise and sour cream until smooth. This is your deliciously creamy foundation.
1 cup mayonnaise, ½ cup sour cream
Add Garlic and Herbs: Mix in the mashed garlic and chopped herbs. If you’re using optional add-ins like dill, oregano, or any of the spices and sauces, add them here and give it a good stir.
Adjust with Buttermilk: Pour in the buttermilk (or milk) a little at a time until the dressing is the consistency you like. Thick for dipping? Thin it less. Runny for pouring? Add a bit more.
¼ cup buttermilk
Chill Before Serving: Cover the bowl and chill the dressing in the fridge for at least 2 hours. This gives the flavors time to blend and mellow out.
Taste and Adjust: After chilling, taste it. Add more salt, herbs, or optional spices if needed. Try it on a piece of lettuce for the best test!
