According to mythology, what was the food of the gods?

In the ancient Greek myths, ambrosia ("immortality") is sometimes the food or drink of the Greek gods, often depicted as conferring longevity or immortality upon whoever consumed it. It was brought to the gods in Olympus by doves, so it may have been thought of in the Homeric tradition as a kind of divine exhalation of the Earth.

W. H. Roscher thinks that both nectar and ambrosia were kinds of honey, in which case their power of conferring immortality would be due to the supposed healing and cleansing powers of honey, which is in fact anti-septic, and because fermented honey (mead) preceded wine as an entheogen in the Aegean world; on some Minoan seals, goddesses were represented with bee faces.

Among later writers, ambrosia has been so often used with generic meanings of "delightful liquid" that such late writers as Athenaeus, Paulus and Dioscurides employ it as a technical terms in contexts of cookery, medicine, and botany. The term was used in connection with different plants.

Additionally, some modern ethnomycologists, such as Danny Staples, identify ambrosia with the hallucinogenic mushroom, Amanita muscaria: "it was the food of the gods, their ambrosia, and nectar was the pressed sap of its juices", Staples asserts.
