Method
- Pour one cup of mayonnaise into a large mixing bowl.
- Add the sour cream and buttermilk, whisking everything together until smooth and fully combined.
- If using dried herbs, sprinkle in dried parsley, chives, and dill, then whisk well to distribute evenly and prevent clumping. Let sit briefly to hydrate.
- Add the garlic powder and onion powder, whisking thoroughly after adding each to avoid clumps.
- Sprinkle in the black pepper and salt to taste, starting with the listed amounts, and whisk to combine.
- If desired for authentic flavor, add the one-eighth teaspoon of MSG and whisk well to incorporate.
- If using fresh herbs, fold in the finely chopped parsley, chives, and dill gently with a spoon to preserve their color and flavor.
- Taste the dressing and adjust seasoning as needed: add more salt or garlic powder if it tastes flat, or whisk in additional buttermilk to thin if too salty or thick.
- Transfer the finished dressing into a clean glass jar or container with a tight-fitting lid.
- Refrigerate for at least one hour before serving to allow flavors to meld and intensify. The dressing will thicken slightly as it chills.
Notes
Make a double batch and store it for up to two weeks. This dressing tastes better on day two or three as the flavors fully develop and meld together.
