I am almost certain that it is honey
It's honey, because it contains natural antibacterial agents. It's not uncommon for fantasy tales of immortality to have honey as part of the formula, as it's been put on wounds to stop them festering for thousands of years.
Water.:)
Honey never ever ever ever ever spoils =D
Yes I'm pretty certain it's honey too. I seem to recall reading that when they opened the Pharaoh's tombs under the Egyptian pyramids, they found jars of honey that were still edible after 3000 years !
That is honey, I have known that for a long time now, and am amazed that there are really not a lot of people out there that know this.
Does water count as a food?
