Add the drained chickpeas from the cans in a pot and cook for another 15 minutes.
Add the boiled chickpeas to the food processor. Add approx. 4 Tbsp of canned liquid, lemon juice, garlic and ice cubes.
Mix at high speed for 5 minutes. You can stop once or twice to lower the chickpeas from the walls of the robot container, so that it is processed evenly.
Add the tahini and leave it to process for another 5 minutes. Add a little salt. Gradually add the liquid from the canned chickpeas, so that you reach a creamy, fine texture.
I do not add olive oil to the robot, but I prefer to sprinkle plenty on top of the hummus. This preserves it even better in the refrigerator, keeping it from drying out.
You can serve it with various toppings or simply with olive oil.
