Truffles Habitat
Like real diamonds, truffles are found underground. Truffles are subterranean tree-
huggers. They are in beneficial committed relationships – symbiosis – with the roots of trees, especially hazelnut, oak, and lime. The tree nourishes the truffle with vitamins and sugars that the truffle, away from sunlight, cannot produce itself, but which it needs. The truffle provides the tree with minerals from the earth. The type of tree to which the truffle bonds accounts for subtle variations in truffle flavor. Truffles are all about terroir. They need unique terrain to thrive. The earth must be soft and damp. It must be rich in minerals. Above all, the soil must be clean. Attempts to replicate Italian truffles in other parts of the world have not been wildly successful. It’s not as simple as planting hazelnut trees someplace, inoculating their roots with spores, and getting some dogs. The Italian micro-climate is much more complex. |
