Drain and rinse the chick peas, reserving 1/3 cup of the liquid. Place all ingredients, minus the chick peas, but including the reserved liquid, in a food processor fitted with the blade. Process until the garlic is well chopped and blended. Add the chick peas and blend until smooth and at desired consistency. Add more salt and cayenne pepper to taste. Cover with plastic wrap and let stand for 30 minutes to allow the flavors to blend before serving. Drizzle with olive oil and serve with pita bread or vegetables. Store in the refrigerate.
