Add the drained chickpeas to a pot and cover with water by a couple of inches. Bring the pot to a boil, then reduce to a simmer.
Cook the chickpeas for about 10 minutes. As they cook, remove loosened skins from the water with tongs or similar instrument.
Drain the chickpeas in a colander, then run cold water over them until the are cool to touch.
Gently rub handfuls of chickpeas back and forth between your palms to loosen the skins. Continue grabbing and rubbing handfuls until most of the skins have loosened.
Place the chickpeas in a large bowl and cover with water by a few inches. The loosened skins should rise to the top and be easy to remove.
To easily take the skin off of individual chickpeas, gently press between your fore finger and thumb until the chickpea pops out.
Place the chickpeas in a food processor and add the tahini, lemon juice, olive oil, sea salt and garlic.
Process on high until the mixture is smooth and creamy.
