Soak the chickpeas for 12 hours. Cook for about 1 hour until soft (5 minutes in a pressure cooker), drain the water and set aside. At the end stir in tahini and lemon juice. Place the mixture in the fridge.
Puree all ingredients from chickpeas to salt in a blender or crush them with a hand blender. A smooth mixture must be created. If the mixture is too dry, add some of the cooking water.
Serve as a starter with tomato and leaf salad or other bites.
