Measure all ingredients into a jar with a tight-fitting lid. Shake vigorously until well-blended and emulsified. Taste and adjust seasonings, adding more salt and pepper if necessary. (Alternatively, you may whisk the ingredients together in a bowl, process the ingredients in a mini food processor, or blend them together in a blender.)
Store leftovers in a sealed container in the refrigerator for up to 2 weeks. Allow to come to room temperature and shake well before using.
If your dressing is too tangy or acidic, you can add a small pinch of sugar or a tiny squeeze of honey to mellow out the acidity.
To make a Creamy Greek Salad Dressing, blend in 2 to 3 tablespoons of Greek yogurt. Taste and increase the salt, if necessary.
