There are white and black truffles: they have some similarities – they’re both a subterranean fungus that grows in the shadow of certain trees. There are over seven different truffle species found all over the world. Depending which country they hail from, they’re sniffed out by specially trained dogs or pigs, then dug up by the “hunter”.
