Truffles are fungi that grow at the base of trees like beech, poplar, oak, birch, hornbeam, hazel, pine, etc. There are over 70 known varieties of truffles of which the white and black truffles are the most desired.
There are many types of truffle oil like black truffle oil, white truffle oil, concentrated truffle oil, etc. The Italian white truffle oil is one of the best oils in the world that contains the essence of truffles of the highest quality. This infused oil is not used for cooking, but is drizzled in small amounts to enhance the flavor of various dishes. Just a few drops of this oil can enhance the flavor of salad dressings.
What is the Oil Made of
Traditionally, Italian chefs prepared their own white truffle oil, by thinly slicing white truffles. They then placed these slices in jars filled with the purest form olive oil available. This helped infuse the rich, distinctive flavors into the olive oil. And this is how this prized oil was made. Most chefs prefer this white because of its milder, earthier, and more flavorful characteristics.
However, most commercial restaurants use inexpensive substitutes, that include synthetically-flavored olive oil containing 2,4-dithiapentane. What's even worse is that most diners fail to notice the difference between the gourmet truffle oil and its substitute. They enjoy their truffle-flavored meal without even realizing they've been served an inexpensive substitute.
Truffle oil is used to add flavor to scores of different dishes. It can be used to accentuate the flavors of meat dishes, pasta dishes, etc. It is also used in fresh bread recipes, sauces, and is also drizzled over salads and mashed potatoes. Some even like to add it to pizzas.
Since truffles are quite expensive and difficult to get hold of, people purchase a bottle of oil, to enjoy the flavor. This oil must be stored in a cool and dark place. However, it must be used within the next few months, because it's prone to spoilage. If you find that the oil has turned rancid, discard it. This is an expensive oil and cannot be wasted. Thus, once you buy it incorporate it in as many dishes as possible.
