What is Truffles?
Truffles are a fungus and grow under the ground as a result of a symbiotic relationship with the roots of particular trees (such as oaks and hazelnuts) infected with the appropriate mycorrhiza (literally, fungus root). While they were originally were confined to the wild, the past century has seen considerable research, particularly in France, into developing the capability of cultivating them as a domestic crop. The truffles form in late summer and slowly mature during autumn and are ready to harvest in winter. They can be found breaking the surface of the ground or down to 200 millimetres deep and are best located by a trained dog, from the aroma they emit when ripening. There are many different varieties of truffle and it is cultivated in the northern hemisphere (Europe and America), and more recently in Australia, New Zealand and Chile.
