Notes
Real buttermilk adds a tangy flavor and creamy texture that can't be matched. If you can't find buttermilk, add a tablespoon of lemon juice or vinegar to a cup of milk and let it sit for about 10 minutes until it curdles slightly.
If using fresh herbs remember that dried herbs are more potent, so use 2-3 times the amount of fresh herbs.
Let your dressing chill in the fridge for at least an hour before serving. This allows the flavors to meld together. It's even better if you can make it a day ahead.
Whisk your dressing well to combine and emulsify the ingredients fully. This will help it stay together and not separate. You can also use an immersion blender or mini food processor for this task.
If your dressing is too thick, you can thin it with a little bit more buttermilk or even some milk. If it's too thin, try adding more mayonnaise or substitute sour cream.
