So, while talking about dwarven sugar and sweet pods, the thought occurred to me that we have all the ingredients for candy under our noses. Honey, ground sugar, fruits, etc. A quick google revealed that the earliest candies were fruits, nuts, and seeds rolled in honey as a preservative, and were very likely used by marching armies due to honey's unique property in the way it doesn't really go bad. Later on, hard candies became popular, basically made from sugar and water and boiled and processed down into a hard nub that was often mixed with spices to create a sort of cinnamon mint variety, and often eaten as it was believed to settle an upset stomach (which happened a lot when these became popular, because not all food was fresh). Then, with factories, cocoa, milk chocolate, and gelatin, a wide variety of candy became available thanks to production line factories.
Now, all this in mind, we have honey and strawberries, prickle berries, and plump helmets. Those are fruits, right? A simple process of combining fruit and honey can produce a simple candy. More complex candies, like marshmallows, would require gelatin made from bone, heating using fuel, and of course a bag of milled sweet pods. We have all of the needed tools and materials here, they're just not put together yet. Candies could have a higher value multiplier, but also need more resources, like 2 strawberries per candy, instead of 1:1 for everything, so they could be a viable trade good, which is believable. Some places like Switzerland probably make a lot of money exporting chocolate (no numbers on hand, but one may assume).
Sweets were also used to preserve food by rolling the ingredients in honey or sugar, and doctors very frequently (and still do) mask the taste of medicine with something sweet. Shelf-life and hospital changes are outside of raw-modding capacity though.
So, any ideas on this to throw out? The basic idea right now is "alternative food source" of sorts, so they'd be used exactly like regular food, because there's no way to mod in a sweet tooth for dwarves.
