The king of the gnomes is facing unprecedented levels of unrest across his lands! It is clear that it will take a grand gesture to regain the support of his people; so, he decides the best way to do this is to declare that their sad old shanty town about must be abandoned. Instead they will build a new happier village entirely of candy.
He feels absolutely certain that his people will love this idea, but when he proposes the idea to the builders guild, they tell him it can't be done. "The rain would destroy their buildings", "The fireplaces would melt", "The city would attract pests wanting to eat the houses", etc.
The builders guild suggests he simply have them make the houses to LOOK like candy, but that is not good enough for the king. He demands "No excuses, only solutions!"
How can the new gnomish village be made out of candy and still be a more-or-less permanent settlement?
In case it is relevant, the population of the town is about 1000 gnomes. The average gnome is about 1 ft.20-30cm (8-12in) tall with a rotund build (think. Think more garden gnome, less fantasy adventure variety). Their overall level of technology is around 12th century Europe; however, their culinary science is on par with the modern day; so, they have no problem making any sort of food products that exist today (sans the modern packaging).
The setting does not actually have to beThere are humans nearby with 16th century technology who are a bit more advanced than the Gnomes in Europe ormost ways, but much less so in culinary sciences.
Magic exists in the 12 centurysetting, I only mentioned that as an example of Gnomish techbut the Gnomes have no access to it.
I am open to a wide range of geographic/climate/environment suggestions; however, the plot requires that the gnomish town be within a relatively short distance to the following: farmlands, a forest, a lake, and a mountain
So... no Antarctica.
The best answer will be one that is easy to understand for a younger reader. Secondary to that, a good answer will allow for a wide range of candies to be used.
