Truffles are a fungus that grows underground at or near the base of trees known as host trees, but not all trees are suitable places for truffles to grow. Typically host trees include poplar, beech, and oak trees. Truffle fungi grow worldwide in many different varieties. They can be distinguished by their color, shape, size, and flavor.
In addition to being a luxury food, truffles can be used to flavor other foods. Truffle oil is a prime example of a versatile use for truffles. Truffle oil has a robust aroma and should be used sparingly to avoid overpowering the other flavors in a dish. It’s most often made from olive oil, which has a smooth, distinct flavor that perfectly complements truffles.
