Truffles are a type of fungus that grows underground in the wild, and they are prized as a delicacy in haute cuisine. They are not mushrooms, though they are both members of the fungi kingdom. Truffles are mostly tubers, like potatoes and carrots, and they have a distinctive aroma and flavour that is lost when cooked at high heat. They are also difficult to cultivate, which makes them extremely rare and expensive. To identify truffles, one must look at the substance they are growing on, their form, texture, colour, and smell.

Truffles are a type of fungus that grows underground near tree roots
Truffles are the fruiting bodies of subterranean ascomycete fungi and are classified into more than 100 genera, including Tuber, Geopora, Peziza, Choiromyces, and Leucangium. They are also ectomycorrhizal fungi, meaning they form a symbiotic relationship with the roots of specific trees, such as beech, birch, hazel, hornbeam, oak, pine, and poplar. This symbiotic relationship allows truffles to absorb water and nutrients from the tree roots, while the trees benefit from the increased absorption of water and nutrients provided by the truffles' extensive system of root-like filaments called hyphae.
The appearance of truffles can vary, but they often resemble small, lumpy potatoes. Their peridia, or outer surfaces, can range in colour, texture (from smooth to warty), thickness, and cellular arrangement. Truffles are typically identified through visual and aromatic cues, as well as chemical tests. The odour of truffles can vary, with some having fruity, nutty, or mushroomy scents, while others may smell putrid.
Truffles are highly prized and sought-after, especially in European countries like France and Italy, due to their distinct flavours and aromas. They are commonly used in small quantities to enhance dishes such as pasta, risotto, and egg dishes. The most common edible varieties are black truffles (Tuber melanosporum) and white truffles (Tuber magnatum), with the former being the most sought-after due to its earthy aroma and taste.
Identifying the specific type of truffle is important, as some varieties, like the Oregon black truffle (Leucangium carthusianum), are not true truffles but belong to a different category of fungi called "ascomycete fungus".

They are prized for their earthy, woody, pungent flavour and aroma
Truffles are a type of edible fungus, specifically the fruiting body of a subterranean ascomycete fungus, belonging to the species of the genus Tuber. They are highly prized in the culinary world for their unique, earthy, woody, pungent flavour and aroma.
Truffles have a complex, earthy, musky and umami-rich flavour. This hard-to-describe taste elevates dishes with just a small amount. Their aroma is intense and unique, with notes of garlic, cheese, oak, nuts, and sweet soil. The white truffle, or Tuber magnatum pico, is particularly pungent, with hints of shallot. Black truffles, on the other hand, have deep, earthy, chocolatey, oaky, and nutty aromas. With over 300 flavour compounds, their taste is intricate and challenging to replicate artificially.
The unique flavour and aroma of truffles are due to their growth process. Unlike mushrooms, truffles grow underground near the roots of certain trees, particularly oaks, in a symbiotic relationship called mycorrhizae. They require specific soil and climate conditions, such as cool winters, damp springs, and hot summers with moderate rainfall. This delicate balance of factors makes truffles rare and difficult to cultivate, contributing to their high value and cost.
The high cost of truffles is a reflection of the numerous challenges involved in finding and bringing them to market. They are elusive and require specialised techniques, equipment, animal assistance, and a keen eye to locate. Their growth is seasonal and limited to a few months of the year, further impacting their availability and price.
Truffles are highly perishable and prized for their ability to enhance dishes with just a few shavings. They are often used fresh, shaved over pasta, risotto, eggs, or meat dishes, as cooking can diminish their delicate aroma. Their intense flavour and aroma make them a sought-after ingredient in gourmet cuisine, adding a touch of luxury to any dish.

Truffles are typically found using dogs or pigs that sniff them out
Truffles are a type of edible fungus that grows underground and has a distinct smell and taste. They are considered a delicacy and are highly sought-after in the culinary world. Truffles are often shaved on top of food or used to infuse dishes with their unique flavour.
Due to their underground growth habit, truffles rely on animals to eat and disperse their spores. As truffles mature, they develop a strong scent and release gases and pheromones that attract animals. This is why animals, particularly dogs and pigs, have been traditionally used to locate and sniff out truffles.
Dogs have been the preferred method for hunting truffles for a long time. Any dog, regardless of breed or mixture, can be trained to sniff out truffles. The traditional Italian truffle-hunting breed is the Lagotto Romagnolo, but other breeds such as Chihuahuas, Corgis, German Shepherds, and even Great Danes have been successfully trained to locate truffles. Dogs are easier to work with than pigs, as they are less likely to damage the delicate truffle fungi while digging and have better endurance.
Pigs, specifically female pigs (sows), are also attracted to the scent of truffles due to its similarity to the sexual scent of a male pig (boar). This method of truffle hunting was common in the past, but it has fallen out of favour due to the damage pigs can cause to the root system of the truffles. In Italy, the use of pigs for truffle hunting has been prohibited since 1985 to protect truffle production.

They are expensive due to scarcity, seasonality, and the difficulty of cultivation
Truffles are the fruiting body of a subterranean ascomycete fungus, one of the species of the genus Tuber. They are highly prized and sought-after, with a unique, rich, and luxurious flavour. They are also extremely difficult to cultivate, which makes them scarce and expensive.
Unlike mushrooms, which grow abundantly all year round and can be cultivated, truffles are seasonal and very difficult to grow. They grow in wild forests and only during a few months of the year. Truffles cannot be planted or tamed, and cultivating them is relatively new and extremely complicated. They are very high-maintenance and require a complex combination of conditions to grow. They are sensitive to their environment and are impacted by climate change, with the number of wild truffles decreasing significantly.
The seasonality of truffles also contributes to their expense. White truffles are typically harvested from the end of September to the beginning of January, while black truffles vary in season depending on the specific variety. The limited harvesting season means that fresh truffles are not always available, and their scarcity during certain times of the year drives up their price.
The difficulty of cultivation and the seasonality of truffles result in their scarcity, which is a key factor in their high cost. Truffles are a luxury ingredient with a unique flavour that is highly sought-after by chefs and food enthusiasts alike, and their limited supply and high demand make them a precious and expensive delicacy.

Truffles are best consumed raw or slightly warmed, not cooked at high heat
Truffles are a type of fungus, specifically, underground mushrooms. They are prized ingredients that are difficult to cultivate and hard to find in the wild. Truffles are distinct from mushrooms in terms of growth, climate, and culinary usage. While mushrooms can be eaten raw, sautéed, baked, grilled, or fried, truffles are best consumed raw or slightly warmed, not cooked at high heat. This is because the cooking process destroys the truffle's characteristic flavor and aroma.
Chefs often shave fresh truffles over pasta, risotto, or egg dishes. When fresh truffles are out of season, truffle butters, salts, and sauces can be used instead. Select Italian producers have also mastered the art of preserving truffles. Truffles can also be consumed in tea form, which can help to prevent some of the adverse side effects that come with eating raw truffles, such as nausea. To make truffle tea, one must chop the truffles finely, boil water, steep the truffle pieces in the hot water, and then add their preferred herbal tea blend.
Truffles are also often chopped into tiny pieces to increase the surface area and make them easier for the body to process. Additionally, chewing the truffles thoroughly when eating them can also aid in digestion. When consuming truffles, it is recommended to do so on an empty stomach, as this can speed up the onset of effects and intensify the experience.
Truffles are highly sought-after due to their powerful flavors and aromas, which are composed of chemicals that mimic mammalian reproductive pheromones. This unique aroma, along with their exceptional taste, makes truffles an expensive and luxurious ingredient in various cuisines.
