What Is Truffle Oil Good For?

Truth About Truffle Oil

Truffle Oil

Truffle oil is derived from either black or white truffle, a subterranean fungus that grows in the roots of trees such as oak,1 and is one of the most expensive food products today.2 It is an earthy, pungent and powerful oil used to add flavor to dishes.3 Black truffle oil is more earthy or chocolatey in flavor, while white truffle oil has a garlicky taste.4

Knowing that truffles are sold at a premium, you may be wondering how truffle oil has become widely available in supermarkets or gourmet food stores. Even simple dishes in restaurants are priced higher when the word "truffle" is added before a dish's name.

This is because truffles are not easily grown and harvested, and are hunted with the help of trained dogs or pigs.5 Once found, the soil must be gently dug up and the truffle carefully removed, as they are fragile.

What Is Truffle Oil Really Made Of?

According to Cook's Illustrated, authentic truffle oil is made by adding truffle oil flavor molecules to olive oil. These molecules may either be extracted from organic sources or harvested from fresh truffles.6

However, most truffle oils sold in supermarkets and specialty stores are just made with olive oil and synthetic ingredients like 2,4-dithiapentane,7 which make them taste just like real truffle oil. Some oils may not even possess the actual taste of real truffles, but because they are more common, many people believe that their taste is authentic.8

If using the real whole food is not an option, I recommend using truffle oil made with authentic ingredients so you can experience the benefits that they provide. When buying, read the labels carefully and watch out for terms like "truffle aroma," "essence" and "flavor." There may be dried truffle bits in the oil, but this is not a guarantee that the oil is authentic.9

3 Truffle Oil Uses in the Culinary World

If you do manage to get your hands on authentic truffle oil, then you must learn how to use it efficiently so as to not let it go to waste. Truffle oil is used as a finishing oil rather than a cooking oil because its flavor changes when it comes in contact with heat.10 Also, remember that it works best in dishes that contain fat such as olive oil, cheese and cream.11 Here are some of the best ways you can use truffle oil:

  • Garnish eggs or pasta with a small amount of truffle oil.12
  • Similar to olive oil, you can use truffle oil as a dipping oil for bread.13
  • Boost dairy-based sauces like béchamel, and unflavored bases like mashed potatoes, polenta and risotto with a drizzle of truffle oil.

Because of its strong flavor (especially if synthetic ingredients are used), truffle oil must be used sparingly to avoid overpowering the rest of the dish. For entrees or appetizers, a droplet is enough.

How to Make Truffle-Infused Olive Oil

Truffle oil's aromatic flavor can easily amp up a dish with a light drizzle. While it's best to use authentic oil so you can fully gain its benefits, you can create your own truffle-infused olive oil by following this recipe.

Ingredients:

1 to 2 small white or black truffles

1/2 cup extra-virgin olive oil

Procedure:

  1. Shave paper-thin slices of the truffles using a truffle slicer or mandoline. The smaller and thinner the truffle pieces, the stronger the flavor of the finished oil.
  2. Place the truffle slices in a small saucepan with the olive oil and warm gently over very low heat for an hour.
  3. Pour the mixture into a small, sterile jar. Close the jar, and then place it in the refrigerator for a week to infuse.
  4. After the oil has infused, pour it through a fine mesh strainer or layers of cheesecloth to remove the pieces of truffle.
  5. Pour the oil into a sterile bottle. Cap and store in the refrigerator for up to 30 days. Remember to take the oil out of the refrigerator about 30 minutes before using.

Note: This homemade truffle oil infusion must be refrigerated and used within 30 days, as this recipe will not preserve the truffles. This oxygen-free oil has a high risk of causing botulism,15 a rare but potentially fatal illness caused by the bacteria Clostridium botulinum,16 which can contaminate various food sources, including infused oil.17
