Rinse and drain the chickpeas in a colander. Add the chickpeas to a food processor along with the red onion, parsley, cilantro, salt, cayenne, garlic and cumin (all ingredients except baking powder and flour). Process the mixture until it forms a chunky paste. A little texture to the mixture is usually desirable. You may need to scrape down the sides of the bowl occasionally to make sure the mixture is an even texture.
Place the mixture into a bowl and stir in the baking powder. Begin adding flour, 2 Tbsp at a time, until the mixture becomes cohesive enough to form into patties. Chickpea or garbanzo bean flour gives the best flavor and texture, but all-purpose can be used in it’s place. Refrigerate the mixture for at least 1 hour to allow the flavors to blend.
Using a small measuring cup or scoop (about 1/8th cup or 2 Tbsp), form the falafel dough into small patties. If freezing the patties for later, place them on a parchment lined baking sheet so they can freeze without sticking together. The patties can be transferred to an air-tight container or freezer bag for long-term storage once they have frozen through.
To cook the fresh or frozen patties, heat oil in a skillet (or pot if deep frying) until very hot and shimmering, but not smoking. Cook the patties on each side until deep golden brown and crispy. Serve with tzatziki, tahini, hummus or stuffed into a pita.
