Caffibeans
Coffee runs the world, and that is especially true for Scorvians. Coffee is such a stable for them, that they genetically modified a species of it to grow wildly and naturally over the volcano walls. The coffee-beans are extremely resistant to hest, and instead of burning up and turning into ash, the heat of volcano cooks and dries the beans over a long period of time, develop long and intense flavors despite only roasting for about s week after maturity.
