For an extra creamy hummus, peel the skins off the chickpeas. This step is optional but recommended.
In a food processor, combine the chickpeas, tahini, lemon juice, garlic, and salt. Blend until smooth.
With the food processor running, slowly add cold water one tablespoon at a time until the hummus reaches your desired consistency. If you have a powerful blender, use 1 or 2 ice cubes instead.
Taste the hummus and adjust the seasoning as needed, adding more salt, lemon juice or garlic to suit your taste.
Transfer the hummus to a serving bowl, drizzle with olive oil, and sprinkle with paprika if desired. Serve with pita bread, fresh vegetables, or use as a spread in sandwiches.
