Peel and crush the garlic, sprinkle with olive oil and let it infuse for 5min.
Drain the chickpeas (reserve the juice) and tip them into a food processor. Add the tahini, lemon juice, oil, garlic, a pinch of salt and some black pepper. Now let the food processor do its magic and mix. After a few seconds, use a spatula to scrape the hummus down the sides and place back in the middle of the food processor. Blitz until you get a smooth paste.
If the past is to thick, add some chickpea water or more lemon juice. Taste and if you think it needs more seasoning add some more.
Transfer to a bowl and serve.
