Begin by finely mincing the garlic and chopping the parsley and dill. Set them aside.

In a mixing bowl, combine the mayonnaise and sour cream. Stir thoroughly until well-blended.

Gradually incorporate the buttermilk, adding it a little at a time until desired consistency.

Add minced garlic, fresh herbs, lemon juice, black pepper, and salt. Whisk until fully combined.

Taste the mixture and adjust seasonings. Sprinkle in cayenne or paprika for an extra flavor boost if desired.

Transfer to an airtight jar and store in the refrigerator. If it thickens, thin it with a splash of buttermilk before serving.
