Truffles are a type of edible fungus, often used in Italian, French, and other haute cuisines. They are highly sought-after and prized for their unique, earthy, musky, and intoxicating flavour and aroma. Truffles are considered a delicacy and are one of the most expensive foods in the world due to their scarcity, seasonality, and the challenges of cultivating and sourcing them. They are often confused with mushrooms, but they are not the same species. While mushrooms grow above ground, truffles are subterranean, growing in specific conditions, usually around tree roots in damp areas. This infographic will explore the differences between truffles and mushrooms, their unique characteristics, and why truffles are so coveted and expensive.

What You'll Learn
Truffles are a type of fungus
Truffles are part of the tuberaceae family and grow underground, usually around the roots of trees in damp areas. They are difficult to find and cultivate, as they only grow in very specific conditions and are seasonal. The most common edible varieties are black truffles (*Tuber melanosporum*) and white truffles (*Tuber magnatum*), with the latter being more expensive and used sparingly due to their intense flavour.
Truffles are considered a type of fungus because they are the fruiting body of a subterranean ascomycete fungus, specifically one of the species of the genus *Tuber*. Over one hundred other genera of fungi are also classified as truffles, including *Geopora*, *Peziza*, *Choiromyces*, and *Leucangium*. These genera belong to the class *Pezizomycetes* and the *Pezizales* order.
The unique flavour of truffles is often described as earthy, musky, and umami-rich, with subtle floral notes. However, the taste can vary depending on the variety, and some people find it difficult to describe. Truffles are best consumed raw or slightly warmed, as cooking them at high heat can cause them to lose their distinct flavour.

They are not mushrooms
Truffles and mushrooms are both members of the fungi kingdom, but they are not the same. While mushrooms are the fruit of fungi, truffles are the fruiting body of a subterranean ascomycete fungus, one of the species of the genus Tuber.
Mushrooms can be cultivated in any season and grow above ground, whereas truffles grow entirely underground and only in very specific conditions. Truffles are seasonal and extremely rare, making them difficult to find and cultivate. They are almost impossible to describe in terms of smell or taste, but they are generally said to have an earthy, musky, umami flavour.
Mushrooms have a woodsy, meat-like taste and a full-bodied flavour, and there are more than 38,000 varieties, with only about 20 species being edible. Truffles, on the other hand, are considered a delicacy and are highly sought-after. They are prized for their culinary value and are used in Italian, French, and other national haute cuisines.
While mushrooms can be fried, boiled, or baked, cooking destroys the characteristic flavour and aroma of truffles. Truffles are best consumed raw or only slightly warmed, and they are often shaved over pasta, risotto, or egg dishes.

Truffles are rare and expensive
Truffles are a type of edible fungus, specifically a member of the Tuber genus, that grow in very specific conditions. Unlike mushrooms, which grow above ground, truffles grow entirely underground, usually around the roots of trees in damp areas. They are considered a delicacy, with an earthy, musky, umami-rich flavour that is difficult to describe and varies depending on the variety.
Truffles are extremely rare and difficult to find and cultivate. They are seasonal, and while they can be cultivated, it is a challenging and time-intensive process. They also have a short shelf life, making them highly sought-after and expensive. In fact, truffles are one of the most expensive foods in the world, with certain varieties selling for as much as $4,000 per pound.
The rarity of truffles is due in part to their specific growing conditions. Truffles grow in a symbiotic relationship with certain host trees, and their spores are spread by animals that eat the truffles and deposit the spores elsewhere. This method of spore dispersal is less efficient than that of mushrooms, whose spores are spread by the wind. Additionally, truffles cannot be planted or tamed, making them even more difficult to source.
The process of harvesting truffles has evolved over time. Traditionally, female pigs were used to hunt for truffles because they have a refined sense of smell and truffles contain androstenol, a hormone found in the saliva of male pigs. However, today's truffle hunters often use trained dogs to locate the fungi, as dogs are less inclined to eat their findings.
The high cost of truffles is a reflection of their scarcity and the challenges associated with their cultivation and sourcing. Their unique flavour and aroma, which is considered a gourmet delicacy, also contribute to their high price tag. For those who cannot afford fresh truffles, there are alternative options such as truffle-infused olive oil, butter mixed with truffle oil or pieces, and other pantry products like truffle salts and sauces.

They have a unique taste and aroma
Truffles have a unique and complex taste and aroma. They are known for their earthy, musky, umami-rich flavour with subtle floral notes. The taste can vary depending on the type of truffle, with black truffles being less aromatic than white truffles, which have a more pungent and intense flavour. White truffles are considered a true delicacy and are usually enjoyed raw and sparingly due to their rarity and intense flavour. Black truffles, on the other hand, are more commonly used in cooking, as their flavour stands up better to heat. They are often used in sauces, compound butters, risottos, and other dishes.
The aroma of truffles is just as unique as their taste. It is often described as "truffle-only", meaning that it is almost impossible to describe and differs from person to person. Truffles are also seasonal, with black truffles available year-round depending on the growing location, and white truffles mainly found in the fall and winter, with their peak season being October to December.
The taste and aroma of truffles are highly sought-after by chefs and food enthusiasts alike. They are considered a gourmet delicacy and are often shaved over pasta, risotto, or egg dishes to add an elegant twist. The cooking process should be gentle, as high heat can destroy the characteristic flavour and aroma of truffles. Instead, they should be cleaned and shaved raw over finished dishes just before serving.
Truffles are also used to infuse olive oil, creating truffle oil, which is a simple and slightly more affordable way to add the luxurious flavour of truffles to homemade dishes. Truffle butter, a compound butter made with truffle oil or truffle pieces, is another way to incorporate the flavour of truffles into cooking. These products allow people to enjoy the taste of truffles even when fresh truffles are not in season.

Truffles are used in cooking
When cooking with truffles, it is important to note that they should not be cooked on high heat as this will cause their musky, intoxicating flavour to be lost. Instead, they should be gently cleaned and shaved raw over a finished dish just before serving. They pair well with foods that have a high fat content, such as butter, cream, cheese and oils, and are excellent on risotto, eggs, soups, potatoes and pasta dishes.
Truffle oil, butter and salts are also popular pantry products that can be used in cooking to add an elegant twist to dishes when fresh truffles are not in season. Truffle oil is simply truffle-infused olive oil, while truffle butter is butter mixed with truffle oil or truffle pieces. These products are slightly less expensive than fresh truffles and can be purchased at gourmet stores or made at home.
In terms of variety, black truffles are often used in sauces, compound butters, risottos and more, while white truffles are usually enjoyed raw and sparingly due to their rarity and intense flavour.
