Ganoderma lucidum
Description
Ganoderma lucidum (reishi) is a hard, cork-like mushroom with a shiny, red-brown cap and a spicy, very bitter, woody taste, which is why it is more often used in the form of dried products or extracts rather than as a chewable ingredient in dishes. From a nutritional standpoint, it provides few calories and macronutrients, but it is rich in polysaccharides (including beta-glucans), triterpenes, and antioxidants, which are associated with immunomodulating, anti-inflammatory, and adaptogenic properties; clinical evidence is promising but varied, so benefits should be regarded generally. In the kitchen, reishi is mainly used for decoctions, teas, broths, tonics, and powders added to lattes, miso soups, or thick umami dishes, where its dried flavor combines with spicy seasonings and richer bases. Store dried reishi in an airtight, dry container in a cool, dark place; keep powders and extracts tightly sealed and use them within a reasonable time (usually several to a dozen months), avoiding moisture.
