The Science
Description
Growing in tight clusters of small caps on slender white stems, Beech mushrooms contain protease inhibitors and beta-glucans that support intestinal integrity. Its micronutrients are easily assimilated during digestion. Though unpleasantly bitter when raw, cooking transforms them into a nutty, sweet, and slightly buttery treat with a firm texture that adds a delicate, functional crunch to various health-conscious dishes.
