Red egg

The myth is that when the planet reaches peace and storms stop all will have the legendary food beet eggs. It is a big deal as the two hemisphere are separated by a giant mountain range, storms make delivery of food imposable and the long distance as the planet is so big from the equator to the north even would spoil foods usually unless they had been preserved. So beet eggs would make it the distance based on being a fermented food, yet the likely hood of making it with a legendary ingredient only taken from the red spot's storm. As a testament to how much a child has grown? That is crazy to most southern tribes. Unless the storms were to end and their was no more storm never ending at the red spot. Also turning the strawberries of the north into vingar instead of enjoying them as sweets is crazy to the northern tribes. Unless no more storms make them more common to find. So all together the food is a myth even though it's doable defiantly. Last is how you need Glyphid red honey which is a death sentence too. Since taking it the glyphids can track you down anywhere with their smell.

Now the basis of this myth is from a rare, but well traveled philosopher. Who loved this food from one taste of it as a child on earth. As on earth it can be made without all these complications. When he reached Jupiter as a ship wreck survivor who was traveling back to Pluto from earth. He found the tribes and their lives too hard. Then came up with this myth.

Known by all social tribes on Jupiter and visitors.
