This was the first hummus I made when I got my new food processor, and I'm never buying it at the store again! I got the recipe from PracticalYoga.tv and followed it exactly. I love the very fresh and bright flavors from the citrus fruits and how well the spices complement them. I eat it as a healthy snack on carrot and celery sticks.
The original recipe notes: "If you are going to use the zest of a citrus fruit it is important that you buy organic, since the outside peel houses most of the pesticides."
Note: Original recipe makes quite a lot. I usually halve the recipe for a week's worth of hummus for two.
