Prepare the ingredients: Drain and rinse the chickpeas thoroughly, set aside. Mince the garlic clove, and juice the lemon to measure 1/4 cup.
In a food processor, combine the tahini and lemon juice. Process for 1 minute, scraping down the sides of the bowl as necessary. This will help create a smooth, creamy base for the hummus.
Add the minced garlic, olive oil, ground cumin, and a pinch of salt to the tahini-lemon mixture in the food processor. Process for another 30 seconds to 1 minute, or until well combined and smooth.
Add the drained and rinsed chickpeas to the food processor. Process for 1-2 minutes, stopping to scrape down the sides of the bowl as needed. The mixture should become smooth and creamy, but may still have some small chunks of chickpeas.
If the hummus is too thick, add one tablespoon of water and 2-3 ice cubes while the food processor is running, until the desired consistency is achieved. You may need 2-3 tablespoons of water, depending on the thickness of the tahini and the moisture content of the chickpeas.
Taste the hummus and adjust seasoning if necessary. You may need to add more salt, lemon juice, or cumin, depending on your preference.
Transfer the hummus to a serving bowl. Drizzle with a little extra virgin olive oil, and sprinkle with paprika or sumac and chopped fresh parsley, if desired.
Serve the hummus with warm pita bread, pita chips, or fresh vegetables for dipping. Enjoy!
