Potato
Potatoes, root vegetables domesticated in South America, spread across the world before the collapse. Gardening communities across the Fifth World continue to grow and enjoy them.
#Human usage
People of the Fifth World use potatoes for food much as people do now. Methods of preparation for the potato include boiling, mashing, and sticking in stews.
#Specialization
A community specializing in relationship with potatoes will invariably practice horticulture, and therefore live in settled villages.
