Begin by washing and cutting the cauliflower into florets. Steam the florets until they are tender, about 8-10 minutes.
In a food processor, combine the steamed cauliflower, tahini, 2 tablespoons of olive oil, lemon juice, lemon zest, minced garlic, and salt. Blend until smooth.
Add water, one tablespoon at a time, blending after each addition until you reach your desired consistency.
Taste your hummus and adjust the seasoning if necessary.
Transfer the hummus to a serving bowl. Drizzle with the remaining tablespoon of olive oil and sprinkle a pinch of paprika on top for presentation.
