2 tablespoons mayonnaise (more or less to taste)
2 tablespoons sour cream (more or less to taste)
3/4 cup buttermilk (preferably whole milk buttermilk)
1/2 teaspoon finely grated lemon zest

2 to 3 teaspoons finely chopped fresh herbs (flat leaf parsley, chives, dill)
1/2 teaspoon freshly ground black pepper, or to taste
Sea salt, to taste
Few drops Sriracha sauce, optional
Place all ingredients in a wide mouth mason-type jar with lid and shake vigorously until combined. Open and taste for seasoning. If a thicker dressing is desired, add additional sour cream or mayonnaise. If a thinner dressing is desired, increase buttermilk. Makes about 1 cup.
