Add everything but the water in a blender. Taste and add anymore tahini, oil, vinegar, salt or lime if you like. If a thinner consistency is desired add water one tablespoon at time until you get the consistency you like. Transfer to a jar with a lid and chill completely. The dressing will thicken more once chilled.

You can add in the cilantro just half at a time. Blend smooth with half then add the rest in and only blend until combined to have larger pieces of cilantro in the dressing.

Dressing will last up to two weeks kept well chilled.
