Whisk the mayo, buttermilk, and sour cream in a medium bowl until smooth.

Step 2

Stir in the remaining ingredients- garlic, herbs, salt, peppercorns,  lemon juice, and vinegar.

Step 3

Taste- you want this slightly salty and tangy- so adjust salt and lemon juice to bump up the flavor.

Step 4

Place in a sealed jar the fridge- and chill. You want this cold!
