In a food processor, add the drained tender chickpeas, lemon juice, lemon zest, tahini, garlic, and salt. Blend until smooth and creamy. If required, adjust the consistency by adding small amounts of the reserved iced aquafaba or iced water (see note 2). Blend again, scraping down the sides of the bowl to ensure a smooth consistency is achieved. Taste and adjust the salt, lemon, and tahini if necessary.
¼ cup Tahini, 1 medium Lemon zest, ¼ cup Lemon juice, ½ teaspoon salt, 1 clove Garlic, ¼ cup Iced chickpea water
