Place all of the ingredients for the dressing in the blender and blend until smooth. Add the tahini last for easier blending.
If your dressing is too thick, add water, a tablespoon at a time, and re-blend until you get the consistency you are looking for. This is a strong dressing and can handle 2-3 tablespoons of water.
Taste your dressing and add salt as needed, a pinch or two at a time, until well-seasoned. Yield: about ⅔ cup.
Notes
Anchovy substitutesNon-vegetarian: 2 teaspoons of Worcestershire sauce or 1 teaspoon of Asian fish sauce plus 1 teaspoon of tamari.Vegetarian/Vegan: 2 teaspoons of furikake seasoning (make sure it is sugar-free) plus 1 teaspoon of tamari.The thickness of tahini varies from brand to brand. If your tahini is particularly thick, you may need more liquid to achieve a dressing consistency. This dressing is very strong and can handle 2-3 tablespoons of water without diluting the flavor too much, just be sure to check your salt after you add it. I've never had to use more than 2 tablespoons.
