Warm the chickpeas (with the liquid) in the microwave for about one minute.
*Optional* If you have extra time and you want to make hummus that is extra creamy, peel the membranes off the cooked chickpeas before you purée them.
In a food processor, add chickpeas and 1/2 cup of liquid and process for 1 minute; scrape the bowl's sides and bottom.
Add tahini (start with ¼ cup tahini), cumin, garlic, lemon juice, and salt. Process for 1 minute.
Scrape the sides and bottom of the bowl; then process for 30 seconds more.
Taste; add more salt, lemon juice, and tahini to your liking.
If the consistency is too thick, run the processor and slowly add a little warm water. Blend until you reach a desired smooth consistency.
Keep refrigerated and serve with pita/chips/Challah
