First, you want to gather everything in one place. Having your ingredients measured and ready makes the preparation smoother. It feels like you are the chef in a cooking show—everything in hand and within reach.

In a medium-sized bowl, combine the mayonnaise, cultured buttermilk, lemon juice, and Dijon mustard. Stir these together until they form a creamy blend. This is the base of your mayo, and the buttermilk is what gives it that delightful tang.

Now, it’s time for the herbs. Toss in the minced parsley, chives, thyme, and scallions. You’ll want to use a spatula to carefully fold in the herbs, ensuring they’re evenly distributed throughout the mayo. This step adds the freshness we all love.

Sprinkle in the white wine vinegar, Kosher salt, and pepper. Taste it to ensure it has the right balance for your palate. Remember that you can always add a little more salt or pepper if needed. It’s all about creating your perfect sauce.

Finally, cover the bowl with plastic wrap and refrigerate the mayo for at least 30 minutes. This step allows the flavors to meld and develop. When you’re ready to serve, give it a quick stir.
