In a food processor fitted with the blade attachment, add cooked beans, tahini, cloves of garlic, lemon zest/juice, cayenne pepper, 1/4 cup of olive oil, 1/2 cup of water, and salt/pepper.
Working slowly, begin to pulse the mixture. Once the beans begin to come together, run the food processor for one minute. You may need to add in more olive oil/water. (Add only a few tablespoons at a time.)
Once the beans have formed a paste, transfer to a high speed blender. With the blender running on low speed, carefully add in the remaining 1/4 cup of olive oil and 1/4 cup of water. Depending on your consistency preference add more/less water/olive oil). Continue to blend for one minute until the hummus is light and airy.
Transfer to a serving dish and place in the fridge for 30 minutes to cool (the high-speed blender can "warm up" the hummus, so you want to make sure to cool it back down quickly).
When ready to serve sprinkle with chopped parsley, red pepper flakes and a drizzle of olive oil. Serve with your favorite pita bread or vegetable and enjoy!
