This is a hummus where the cauliflower stands in for the chickpeas, so it is lighter both in texture and flavor. The garlic is blanched as well so the sweetness of the cauliflower stands out, but if you like, feel free to use raw garlic for a more assertive flavor. Using garlic roasted in its skin would enhance the sweet and nutty flavor of the cauliflower while backing off the heat and breath enhancing qualities of raw garlic. Use this where you would traditional hummus.
