What are Truffles?

Before you can understand what truffle oil is and how to make it yourself, it’s a good idea to have a crash course in truffles in general. Most people tend to think of truffles as a mushroom, but they actually aren’t quite a mushroom at all. They’re distant cousins of mushrooms since both are a type of fungus, but that’s pretty much where the similarities stop. However, truffles do tend to have a flavor that pairs well with mushrooms because of their similar growing habits.

kinds of truffles

Most truffles grow on the roots of certain types of trees. Many of these trees are nut trees, such as hazelnut or beech trees, but they may also be found on oaks, poplars, and birches too. The truffles are more or less a fungal infection on the trees which grow in their root systems. However, they don’t damage the trees, and in fact, they lend a lot of benefits to their host trees throughout their lifetime. The tree and the truffle form a symbiotic relationship. It can be damaging to the tree to harvest the whole truffle growth from its roots.

It takes a very special climate to cultivate truffles, which is largely why they aren’t available everywhere in the world. Parts of northern Europe have the best climate for truffle growing, so some of the biggest, most flavorful, and most valuable truffles can be found in these regions of France and Italy. More and more frequently, however, truffle growers have been successful in the United States as well as in other climates around the world.

There are a few different types of truffles, which we will explore in the next section. Understanding the different types of truffles can give you a good starting point for knowing the difference between the truffle oils you’re likely to encounter.

Different Types of Truffles

It’s true that there are quite a few different truffle species out there in the world, but two of these remain the most widely popular, well-recognized, and highly sought after. You’re most likely to come across truffle oil made from either black or white truffles, but the differences don’t stop there. When shopping or making your own truffle oil, you might find bottles and recipes that use a specific type of truffle in the process. It’s a good idea to recognize the differences between these before you get started.

  • Black Truffles – There are two types of black truffle: winter and summer. The most valuable black truffles grow in the Perigord region in northern France, but other types can be found throughout Europe. Winter black truffles are considered more valuable than summer ones since their flavor is stronger and they have an overall better aroma and texture too. Summer black truffles are less flavorful, but have a nice taste and aroma and they tend to cost much less.
  • White Truffles – Like black truffles, white truffles come in both winter and summer varieties. White winter truffles are among the most expensive in the world, and those that are harvested from the Alba region in Italy often top the price lists at major truffle auctions worldwide. If you’ve ever heard of a truffle that sold for an inordinate amount of money, it was probably a winter Alba white truffle. Summer white truffles are found throughout Europe, but they aren’t usually found many other places in the world.
  • Pecan Truffles – These are much lower quality truffles that, for a long time, were regarded as garbage and simply thrown away. In recent years, they’ve begun to be more popular as gourmet cooking ingredients. They are grown on the roots of pecan trees and can most commonly be found in Texas and North Carolina. They are a type of black truffle.
  • Oregon Truffles – Oregon truffles come in both black and white varieties, although black Oregon truffles are much more common. These truffles grow well in the Pacific Northwest and are comparable to black summer truffle from Europe in taste, aroma, and texture.

Differences Between Truffle Oils

Just like fresh truffles, truffle oil has a few different varieties. You are most likely to come across truffle oil and recipes for making your own truffle oil that focus on either white or black truffles without specifying which types to use. In this section, I’ll detail both variations of this popular ingredient so you can decide which version you’d like to try making first. Once you choose the type of oil you’re interested in, you can move on to learning how to make truffle oil.

Black Truffle Oil

Black Truffle Oil

Black truffle oil is a little bit less common than white truffle oil in cooking. However, you’re still likely to come across it in recipes, so it’s a good idea to understand what types of food work best with this oil and which flavors you can expect from it.

  • Black truffle oil, like black truffles, has a very earthy and deep flavor. It has a musty aroma that you can smell as soon as you take the top off of its container.
  • Some people have compared the taste of black truffle oil to chocolate and red wine. It has a bit of an ammonia smell, but that smell is overwhelmed by the earthiness of the oil for the most part.
  • Black truffle oil can be used in small quantities as a cooking oil, especially if you choose to use it for cooking mushrooms or beef. For the most part, however, it works best as a finishing oil. It’s never a good idea to use black truffle oil in large amounts for cooking.
  • While beef and mushrooms are great uses of black truffle oil, you can use this tasty ingredient in many other types of food as well. Try it in heartier dishes like pork chops, pot roast, and even pizzas with meat toppings.
  • One of the best uses for black truffle oil is to drizzle it over your cooked bread and grain dishes such as flatbread and pasta right before consuming. It also tastes great when mixed into some rice.

White Truffle Oil

White truffle oil is more common, especially in restaurant quality food. This is a lighter oil with a bit less overwhelming of a flavor, which makes it useful for a variety of different foods. Before you make your own, familiarize yourself with the types of recipes you might want to use it in.

WhiteTruffle oil
  • White truffle oil has a very similar flavor and aroma to white truffles. However, eating a fresh white truffle is sure to give you more flavor than you could get from white truffle oil. This is because white truffles are very light, so the full force of their flavor can’t quite infuse into the oil.
  • Regardless of this light quality of white truffle oil, it remains very popular. The lighter flavor can really accent certain ingredients, and when you use white truffle oil with certain foods, you can make the taste of the truffle come through beautifully.
  • The aroma associated with white truffle oil has an ammonia-like quality, which may be off-putting if you’ve never smelled it before. This may turn some people away from tasting this delicious ingredient, but bear in mind that the smell isn’t the same as the taste. The flavor of the oil is a bit tangy and zippy, with a hint of garlic and onion throughout.
  • Because of the garlic-like flavor of white truffle oil, it works beautifully in Italian dishes. It blends nicely into pasta dishes, and it is also delicious on chicken. White truffle oil risotto is another popular dish that incorporates the tasty flavor of this light oil well.
  • White truffle oil has a flavor that doesn’t work well as a cooking oil. It should be used as a finishing oil in almost every instance. The ammonia smell may become too strong when this oil is heated for too long, and the nicer flavors in the oil may cook away. Because of this, it is best used for drizzling over your food at the last minute, or for just heating through.
  • If you can’t think of any other way to use your white truffle oil, try mixing it into some fluffy, warm scrambled eggs. This is one of the most delicious and simplest ways to enjoy this great ingredient.

Tips and Tricks for Making Your Own Truffle Oil

When you follow the methods listed above, you can make delicious and flavorful truffle oil that works well in any recipe you want to prepare. However, there are a few tips and tricks you can keep in mind when you want to improve the quality of that oil and keep it fresh for as long as possible. Check out the tips listed below to make your homemade truffle oil experience even better than ever before.

  • Heat your truffle oil if you’re keeping it in the refrigerator. Oil kept in the refrigerator is prone to separating or becoming opaque and thick. This doesn’t mean that it’s spoiled! Simply put it in a double boiler or heat it in a saucepan very slowly over low heat until it becomes clear again. This can help you bring life back into oil that has been stored a little too long.
  • Consider storing your oil in a bottle made for winemaking. You can purchase sets made for making wine at home that include bottles that can be sealed in unique airtight methods. This can help you store your truffle oil and keep it fresh for even longer.
  • Leave the truffle pieces in your oil as long as possible. The longer you let the pieces of truffle steep in the oil, the more flavorful the oil will become. However, try not to leave the pieces in the oil for more than three days. This may cause more bacteria to grow in the oil, which could cause you to become ill. Three days is usually the limit, but try to steep the oil at least 12 hours if possible.
  • Never use low-quality oils. Only high-quality oils should be used because these are much better in terms of flavor as well as the ability to soak up the taste of the truffles. However, olive oil is not the only type of oil you can use. Don’t be afraid to branch out and try other oils, but be sure to stick to quality options.
  • Keep water away from your oils. Although water and oil repel each other and the water won’t mix into your oil, you can still cause a decrease in quality in your truffle oil if it becomes too wet. Try to keep water from getting into your storage container, and if you will be reusing a bottle or jar you’ve already used in the past, be sure to wash and dry it out well before storing truffle oil in it.
