Although originating in South America, the potato is, peculiarly, closely linked to German identity. Inconspicuous, misshapen, and underestimated, Solanum tuberosum interested me for these very qualities. And so I set out to research this tuber.

Over the course of one year, I collected beetles from its leaves, buried rolls of film in its soil, planted my own patch of potatoes, and visited the fastest peeler in the country. I have repeatedly boiled, fried, and eaten potatoes.
My investigation took me to the harvester, laboratory, gene bank, greenhouse, and barn—but also to the georesearch centre and phytopathological collection, a king's grave, and my home village.

I now realise the potato has not only shaped world history, it also has great plans for the future and will—perhaps, perhaps—one day even thrive on Mars.
