Drain the water. Pour chickpeas with fresh cold water. Do not salt! Bring to a boil, cook the peas over low heat until tender (about 2 hours). Pour the water into a cup (the broth is useful, do not pour it out).
Pour spices to taste and cumin into a dry frying pan. Heat, stirring, for 2-3 minutes, until a light aroma appears. Pour the spices into a coffee grinder, grind.
Pour sesame seeds into a dry frying pan, lightly fry the sesame seeds, stirring occasionally, until light golden brown and pleasant smell (2-3 minutes).
Peel the garlic.
Cool sesame seeds, grind in a coffee grinder.
Put spices, garlic, salt, olive oil, ground sesame seeds in a blender. Beat everything well.
Add portions of boiled chickpeas. Beat everything well until puree (add a little chickpea broth to achieve the desired consistency of hummus). So chop up all the chickpeas. Season to taste with salt and lemon juice. Beat everything well again. Homemade hummus is ready.
Place homemade hummus in a bowl and pour over with olive oil. Let it brew in the refrigerator for 2-3 hours.
