Panonvomadon Kun Vermoj

Zemetan salty bread - known by the locals as "panonvomadon," literally 'vomit inducing bread' - is largely considered the single worst foodstuff served anywhere in Pretheya. It is not intentionally made, but rather occurs by accident when the bread making process is contaminated by salt; which happens all too often within Flame's Providence, owing to the inescapable prevalence of salt within the region.
Owing to the scarcity of food within Zemet, even such malformed bread cannot just be thrown away, and often must be consumed. In order to make it more bearable, it is sometimes soaked in beaten eggs and sugar, in order to mask the taste of the salt; at which point it becomes almost palatable.
In time, however, Ashborn youth came up with an alternate use for the dish. It was eventually realised that the many foreign merchants and pilgrims that pass through Flame's Providence on the daily - either to trade or visit the various holy sites within the city - were unfamiliar with the horrors of Panonvomadon, and could be tricked into purchasing it under the guise of 'traditional Ashborn cuisine.' It became a sport among the youth to set up stalls and see who could cause the most foreigners to choke on the inedible substance, with extra points being awarded for those who could not even keep the first mouthful down and spat it out in front of the shopkeeps.
Eventually, however, the practise evolved into an even more wicked form, as the ones running the scam realised that they could pass the dish off as a separate meal by placing cooked Salvermos upon slices of the bread. This was equivalent to pouring more salt upon the already salty meal, and had the effect of turning it from something merely unpleasant to straight up inedible. Described as 'akin to shoving a pile of salt into one's mouth,' the dish was responsible for causing several wealthy merchants to fall ill and require medical assistance; after which point the authorities in Flame's Providence finally cracked down on the practice of selling it.
Although no longer used to menace unsuspecting travellers, the legend of the worm bread hawkers continues to remain a popular tale among the city's youth even to this day.
