What Are Truffles?
Truffles, like their mushroom relatives, are a type of edible fungus. However, they grow underground near tree roots, particularly oak trees. Despite being part of the fungi family, Tuberaceae, truffles have gained a reputation as a luxury food item due to their unique flavor and aroma, which many describe as earthy, pungent, and musky.
Why Truffles Come with a Hefty Price Tag
Truffles are a coveted delicacy found in places like France and Northern Italy, particularly in the Piedmont region. Their high cost is due to a combination of factors such as their seasonal availability, unique growth requirements, and the labor-intensive process of finding them.
Truffles grow underground near the roots of certain trees, benefiting from a symbiotic relationship called mycorrhizae. They require specific climate conditions, consisting of cool winters, damp springs, and hot summers with moderate rainfall. Additionally, truffles take about six to seven years to fully develop, and you cannot simply plant them in a regular garden.
Regarding their harvest, truffle hunters rely on the keen noses of specially trained dogs. Since humans cannot detect the aroma of underground truffles, these dogs play a vital role in locating these delicacies, often under the cover of darkness.
Given their complex growth requirements, seasonal nature, and the labor involved in finding them, it is no surprise that truffles stand among the most expensive foods in the world.
Types of Truffles
Black Truffles
Black truffles are known for their chocolate-like notes and deep, earthy, oaky, and nutty aromas. With over 300 flavor compounds, their taste is intricate and challenging to replicate artificially. There are various edible black truffles, and since they’re quite pricey (over $100 an ounce), it’s essential to know what you’re buying. The most sought-after variety is the Tuber melanosporum, often known as the Périgord truffle or winter truffle. This truffle can be found in Italy and France, as well as cultivated around the globe.
The Tuber aestivum or summer truffle is another variety of black truffle. Generally less expensive and less potent, it can also be cultivated and is currently grown around the world. About 95 percent of French black truffles are cultivated, according to experts. Interestingly, the Burgundy truffle, or Tuber uncinatum, is the same species as the Tuber aestivum, but the two varieties flourish in slightly different environments.
White Truffles
White truffles are a different story, as they cannot be cultivated like black truffles. This makes them rarer, more valuable, and only accessible from September to December. The Tuber magnatum pico, also known as the tartufo d’Alba, Piedmont, or white truffle, is primarily found in Italy. Its aroma is reminiscent of oak, nuts, and sweet soil, which explains why it’s up to five times more expensive than black truffles, even selling for as much as $4,000 a pound.
In Oregon, you’ll find a unique white truffle species, the Tuber oregonese. It has a distinct aroma compared to its European counterparts, often described as more herbal and floral.
The Finest Method to Savor Fresh Truffles
If you manage to acquire some fresh truffles, make sure to utilize them promptly and thoughtfully. Use your truffles as soon as possible because their delectable aroma fades quickly. An excellent tip is to store them in a sealed container with fresh eggs, allowing the truffle aroma to permeate the yolks in just 48 hours. You can then create delicious omelets or scrambled eggs with these truffle-infused eggs.
Black truffles are best when added as a finishing touch to dishes. They can be placed atop fish or beneath the skin of a chicken to enrich the flavor. However, white truffles should not be used for cooking; they shine when added fresh to a dish as a finishing touch. Creating white truffle butter in small batches helps to preserve their unique taste.
To make the most of your truffles, use a microplane or truffle shaver to unleash their flavors. Raw truffles served cold lack flavor, so always add them to warm dishes. As their aroma compounds dissolve in oil, it’s advised to serve truffles with meals containing eggs, butter, cream, or cheese. You can also drizzle truffle oil or sprinkle truffle salt to enhance the taste. Combining them with ingredients like garlic, shallots, grated potatoes, and even steak provides a heavenly dining experience.
Now, get ready to experiment with various recipes that incorporate fresh truffles, truffle butter, or truffle-infused oils. With these suggestions, you will surely impress your taste buds and elevate your cooking game. Remember, a little finishing garnish of truffles goes a long way!
