Truffle oil is simply a food grade oil that fresh or dried truffles (similar to a mushroom) have been added to. The exotic fungus saturates the oil with all of its earthy, umami flavor - giving cooks an affordable way to get that delicious flavor in all kinds of dishes. Read on for everything you need to know about types and varieties of these fungi, as well as how to use them.
What Is Truffle Oil?
It originated as a way to add the luxurious flavor of truffles to dishes without the extreme cost of the fresh product. In order to make it a light oil is infused with pieces of truffle and stored until the it carries both the flavor and scent of the fungus.
All Oil Is Not the Same
With the popularity of food shows, food reality television, and celebrity chefs more home-cooks are using exotic ingredients than ever before. Saffron, wild caught salmon, and truffles used to be ingredients found only in five star kitchens but today these ingredients, and thousands like them, are available to almost everyone.
While there are plenty of truffle oils available commercially you have to be careful - some of them are chemically flavored while others taste like a slice of truffle has been waved over it for a few seconds.
The really good kind is not cheap - but you can make it yourself relatively inexpensively.

What Is a Truffle?
Simply put, it is a fungus like a mushroom but grows underground near certain species of trees. The type is dependent on the type of tree it grows by.
It reproduces by spores like other fungi, however since the spores of a truffle cannot be released underground they are spread in the feces of the animals that eat them.
How Are They Harvested?
Finding truffles is traditionally done with a "truffle hog". This is a female pig that naturally searches for the treat as part of her diet.
Recently dogs have begun to be trained to sniff out this delicacy because it is difficult to keep the pigs from eating the harvest!
