Prepare the hummus: Add all the ingredients, except for the aquafaba, to a food processor. Blend for 2-3 minutes until the hummus is smooth. Check the thickness and creaminess, and if you want a thinner or creamier consistency, run the food processor and slowly add the aquafaba one tablespoon (15 ml) at a time until you reach your preferred texture.
