What Is the Most Expensive Food in the World?

Truffles hold that honor. Like the mushroom, the truffle is a fungus. Some truffles are just the size of a pea, while others are as big as an orange. These black fungi grow in parts of France and Italy. They are used most often in small amounts to give a flavor to certain dishes, especially sauces.

It's a good thing that truffles are used in small amounts, because they are the single most expensive food item in the world. Truffles usually cost more than $100 a pound, with the best truffles costing well over $200 a pound!

Truffles grow underground, and are very hard to find. Farmers use trained pigs to locate truffles. The pigs sniff around until they pick up the scent of a truffle, then begin to dig. The farmer chases the pig away and digs up the truffle for himself. If he's not fast enough, though, the pig will dig up the truffle and eat it. And at $200 a pound, that's an expensive meal for a pig!

Though truffles are the most expensive food in the world, they have no vitamins or other nutritional value!

Who Invented Potato Chips?

According to a story that may or may not be true, the first potato chips were 'invented around 1865 by a chef in Saratoga, New York.

The chef made a batch of thin-sliced potatoes for the diners at a guest house, but one of the guests kept sending the potatoes back and asking for thinner slices. So the chef cut a potato into the thinnest slices he could, dropped them into oil, and produced America's first potato chips!

The first factory in America built solely to produce potato chips opened in Albany, New York, in 1925.
