You can buy falafel mix either in the box or in bulk. Mix about half a cup of water for every cup of mix. 1 cup of mix makes about 6-8 falafel patties. Mix together periodically while letting it mix and settle for about 10 minutes. Use a spoon to shape your new batter into appropriately sized balls and drop into oil deep enough to cover half of the patty. I use a wok, but you can use whatever suits you best. Try to use as small a pan as possible so that you aren't wasting a lot of oil. Make sure the oil is already hot, heated at a medium-high level. Flip your falafels once, once they look brown enough for your satisfaction.
As you can see I ate my falafel with tomato (diced for maximum pleasure), boston (or butter) lettuce, although I recommend romaine and sauteed red onion and portobello mushrooms. I also recommend turnip as a staple in most falafels, but I didn't have any today. I also prefer my falafel with hummus, which I am also out of. Other delicious additions could include a variety of peppers, olives, tzatziki and even pineapple. Be creative and enjoy!
