Place all the dressing ingredients: fats, acids, and spices (except the olive oil and water) into a food processor and blend until smooth. Scrape the sides with a spatula, if necessary.
With the processor running, slowly drizzle the extra virgin olive oil into the dressing.
Thin the dressing with a little water, then taste and adjust seasonings. Add a bit more acid (vinegar, buttermilk, or lime juice) if necessary.
Use a spatula to remove the dressing from the food processor and pour it into a bowl or jar. Cover and refrigerate in an air tight container to chill for an hour or two to a maximum of 5 days.
