What are truffles?
Truffles are edible fungi that grow underground among the roots of certain trees. It’s a complementary relationship in that truffle fungi help the tree absorb water and nutrients, and in return, the tree’s roots provide sugars needed for the fungi to thrive. So truffles are not just a luxury food, they’re vital to the ecosystems they inhabit.
