Truffles are rare and precious aromatic mushrooms that grow underground, generally near the roots of trees. They are known for their intense and unique flavor and smell, which have made them one of the most expensive and coveted ingredients of gastronomy. There are many species of truffles, but the two most commonly used in the kitchen are black truffle and white truffle. The black truffle, also known as the winter truffle, is more common and less expensive than white truffle, but it also has a stronger taste and odor. The white truffle, also called summer truffle, is rarer and more expensive, but it has a more subtle and delicate flavor. Truffles are often used in the kitchen to flavor dishes, especially sauces, omelettes and risottos. They are also often grated on the dishes to add a touch of flavor. Although their high price can be intimidating, a little truffle can go far and add a luxury level to any meal.
