Wash the lemon, then zest and juice it. Peel the garlic.
Add the chickpeas, lemon juice, olive oil, and garlic to a blender or food processor: purée until smooth. Next, add the tahini, lemon zest, and cumin and season with salt and a pinch of sugar.
If the hummus is too thick, add a splash more oil until it reaches your desired consistency.
Notes
Pita bread goes just as well with lemon hummus as falafel. Veggie sticks, grilled food, or meatballs alike will also benefit from a dip in this refreshing spread.
