COMBINE all ingredients, except for the remaining reserved chickpea liquid, in a mixing bowl.
PURÉE with a stick or immersion blender until smooth, adding 1/8 cup of the reserved chickpea liquid at a time, if the hummus mixture is too dry.
Alternatively, PURÉE mixture in a food processor or high-speed blender until smooth (again, adding additional liquid, if need be).
SPOON hummus into a pretty serving bowl, making a shallow well with the back of your spoon in the center.
FILL the well with a good-quality olive oil and sprinkle with paprika.
