Add chickpeas into a small pot. Cover with water and add baking soda. Bring to a boil over high heat. Reduce heat to medium-high and let boil until soft, about 20-25 minutes.
Drain chickpeas in a fine mesh strainer under cool running water until water runs clear, about 20 seconds.
Transfer chickpeas to a food processor with tahini, lemon juice, olive oil, garlic, cumin, salt and pepper. Process until smooth, scraping down the sides with a spatula when the hummus gets stuck to the walls of the bowl. Process once more. With the food processor running, drizzle in 2 tablespoons of the ice cold water. Process until smooth and creamy. (If your hummus is too thick if using a thick tahini, blend 1-2 extra tablespoons of cold water into your hummus until reaching your desired consistency.)
Taste test and adjust flavours if necessary: extra pinch of salt or cumin, or a little extra lemon juice.
To serve, drizzle with olive oil and sprinkle with a light dusting of paprika.
Notes
Tips:
If you're using tahini, blend in two extra tablespoons of water for extra smooth consistency.
