The fungus kingdom, which is distinct from the kingdoms of animals and plants, includes mushrooms. Like plants reproduce, they renew on their own through germinating their spores. They digest the nutrients they exude rather than consuming food or light like plants and animals to thrive. Cooks often employ mushrooms, particularly in Asian and European cuisines.

Because of their high water content, spongy texture, and mild flavor, mushrooms are very adaptable in the kitchen.
