America's Top 10 Favorite Street Foods

Grind up some chickpeas, add garlic, parsley and coriander, and fry until crunchy. According to some, it's a recipe as old as the Bible. In all likelihood, it's even older, having started out in Egypt as a dish made with fava beans. But even today, falafel's origins are in dispute. Some Israelis claim it as an ancient Jewish food, while many Palestinians bristle at the idea. Cooler heads maintain that falafel is a regional delicacy, not a religious one. But politics are of little consequence when you're standing on the sidewalk at lunchtime waiting for your favorite vendor to wrap some pita bread around a selection of pickled beets, tahini sauce, fresh veggies and, above all, crispy, delicious falafel.

If you live in Chicago, it's a beef frank and you eat it on a poppy seed roll with mustard, relish, onions, pickles, tomatoes and celery salt. If you're in Rochester, N.Y., it's a spicy pork sausage -- split, grilled and nestled in a toasted bun. The varieties are as endless as the stories of its origins. Are they called franks because they were invented in Frankfurt, or are they called wieners because they come from Wien (aka Vienna)? Nobody knows for sure, but one thing's certain: A hot dog's not a hot dog until it's sitting in a bun. And that important innovation is all-American.

Archaeologists have dug ancient pizza ovens out of the ash of Pompeii in southern Italy. But the classic pizza that we've come to know and love wouldn't exist without a little help from the New World. When the tomato was first brought to Europe from South America, the upper classes refused to eat it because they were convinced it was poisonous. But peasants were too poor to be picky, and they started spreading the red fruit on their pies. Several centuries later, fresh basil and mozzarella were added, and the classic pizza Margherita was born. Today, U.S. pizza toppings are as varied as the American palate. From pineapple to pickles, the only limit is your imagination.

Steamed or grilled, filled with beef or rice and beans, all burritos start with the same round, flat flour tortilla. They probably get their name from an old Spanish saying: "If I had a horse, I would go make my fortune, but I only have a little donkey." In Spanish, the word for "little donkey" is "burrito." Like its animal namesake, the burrito can carry anything: beans, rice, sour cream, cheese, avocados, chicken, beef, pork. You name it. In Sonora, Mexico, their likely birthplace, burritos are small, simple affairs, but over the decades, as burritos made their way north and west to their modern day capital, San Francisco, they grew in size and complexity until they became a great Mexican-American delicacy.

The Greek word gyro means "spin," and that makes sense when you think of those huge cones of mystery meat spinning on their axes in sidewalk restaurants around the world. Before it became street fare, the gyro was popular long ago in Greece. Traditionally, these meat cones were made by hand from a combination of beef and lamb trimmings, breadcrumbs and oregano. Then, one day in Milwaukee in the early 1970s, a Jewish-American entrepreneur named (believe it or not) John Garlic was brainstorming with his wife Margaret when they dreamed up the idea of mass-producing that spinning meat. Voila -- Old World met New World to create an enduring street-side favorite.

Legend has it that in the 1930s, the great French chef Charpentier invented crêpes suzette with its signature orange sauce for the future King Edward VII of England. But long before that, it was the favorite food of French peasants. Originating in Brittany in northwest France with the simple ingredients of buckwheat flour, eggs, butter and milk, the crêpe has proven to be one of the most versatile foods ever created. Made on the spot by sidewalk vendors around the world and filled with everything from cheese and ham to strawberries and cream, crêpes are beloved by all.

Frozen cream and sugar: simple, yet perfect. Was it invented in the 1600s in the court of Charles I, or even earlier by the Emperor Nero who sent slaves to fetch ice from the mountains? Actually, the historical record points to ancient China as the birthplace of the world's favorite portable dessert. It was in 1774, on the eve of the American Revolution, that ice cream first arrived in the United States. But it took nearly another century before an ingenious New Jersey woman named Nancy Johnson invented a hand-cranked ice cream maker and America's love affair with that miraculous confection took off. Chocolate or vanilla, scooped or soft-served, in a cone or a cup -- maybe some of ice cream's popularity is due to its versatility. After all, you can opt to sit down to an elaborate banana split concoction, or you can just walk down the sidewalk with a waffle cone and let your favorite flavor melt in your mouth.

This delectable breakfast pastry owes its name to its unusual curvy shape. Once upon a time, Spanish shepherds stuck high in the mountains for days on end became desperate for a treat. Using the limited available ingredients of butter, eggs and flour, they concocted a fried pastry that resembled the horns of the sheep they tended. Those sheep were called churros. In time, that humble shepherds' food made its way to Latin America and then north to the United States. In recent decades, Americans have taken to churros with gusto. Dusted with sugar and served with a steaming cup of hot chocolate, churros make an amazing sidewalk breakfast.

For hundreds of years, aristocrats savored delicate webs of sugar spun by elite chefs, but for regular people, that sweet, melt-in-your-mouth sensation was far too expensive. Then, in 1897, John C. Wharton and William Morrison invented a machine that melted and spun the sugar with ease. In 1904, they brought their machine to the St. Louis World's Fair, where it was a huge success. In the 1970s, a further innovation fully automated the process all the way through packaging the confection in paper or plastic bags. Today, it's hard to imagine a street fair without those pink, azure and ultramarine clouds of what used to be called fairy floss.

In 610, a monk twisted some leftover dough into the shape of crossed arms and gave it to children as a reward for learning their prayers. Pretzels were a hit across Europe, and nine centuries later, when the Turks were tunneling under the walls of Vienna, it was the early-bird pretzel bakers who heard them and sounded the alarm. Even today, the coat of arms of the Viennese bakers proudly bears a pretzel. But it was the Pennsylvania Dutch who perfected what would become a famous Philly snack. According to The New York Times, the soft pretzel, sprinkled with salt and smothered in mustard may be the definitive street food.
