Named after the French Périgord region, black Périgord truffles (lat. Tuber mélanosporum) grow nestled in the roots of hazelnut and oak trees and are typically harvested during autumn and winter.
Bulbous and irregularly shaped, the truffles are full of white veins on the inside. They are characterized by their unique, pungent, and earthy fragrance. When fully mature (from December to March), they release their distinctively musky and slightly sweet flavor, which is why Périgord black truffles are one of the most expensive edible fungi in existence.
