What is a Truffle?
Truffles are a type of fungus that grows underground and maintains a symbiotic relationship with the roots of specific trees, like oak, hazel, and beech. They belong to the Tuberaceae family and are renowned for their pungent aroma and distinctive, earthy flavor. These elusive delicacies come in various species, with the most sought-after being the black truffle (Tuber melanosporum) and white truffle (Tuber magnatum).
Secrets of Truffle Harvesting: Tradition and SustainabilityTruffle harvesting involves a mysterious and time-honored process. It begins with secret locations where truffles grow, passed down through generations. Specially trained truffle dogs, often breeds like Lagotto Romagnolo and Springer Spaniel, use their keen sense of smell to pinpoint ripe truffles hidden underground. Truffle hunters gently unearth the delicacies, leaving the surrounding environment undisturbed for future growth. Cleaned and graded based on size and quality, truffles are carefully handled for maximum quality. This process ensures a delicate balance between tradition and sustainability, preserving the truffle's ecosystem for future generations.
