Japanese matsutake mushrooms are the most expensive mushrooms in the world. Fetching up to $500 per pound, they rival truffles and are considered one of the most valuable ingredients of Japanese cuisine.
Matsutake, or mattake mushrooms grow on the Korean Peninsula, in China, and even in the United States, but only the ones harvested in Japan, especially around the Kyoto area, fetch truly mindblowing prizes. While imported Matsutake can cost around $50 per pound or less, Japanese mushrooms can cost up to ten times as much. To help Japanese buyers discern between imported and home-grown matsutake, Japan has a law that requires imported mushrooms to be washed of dirt before commercialization, while the domestic variety has a rough, grubby appearance. Japanese matsutake are prized for their strong aroma, meaty texture, and earty taste.
