Strain the chickpeas and boil them in water without salt for 1 hour until they are soft. Catch the cooking water.
Peel the garlic and mix with the chickpeas and the remaining ingredients in a blender or with a hand blender to a creamy paste. Add a few tablespoons of the cooking water.
Serve garnished in a bowl with a few drops of olive oil and fresh parsley. Goes well with fresh ciabatta or as a dip with vegetables.
