Combine all ingredients in a jar or salad dressing bottle with a lid. Shake well to combine. (You can also whisk together in a small glass measuring cup and then pour into a salad dressing bottle for storage.) I have done both.
Refrigerate for a few hours to let the flavors develop.
Take the dressing out of the refrigerator about 10-15 minutes before you are going to use it to allow the olive oil to come to room temperature. (It will solidify in the fridge). You can also run the jar under warm water to help speed this process along if needed.
