If I trust Wikipedia, even today the term "Erdapfel" is used to refer to topinambour in some regions: "Mancherorts in Baden wird Topinambur als Erdapfel bezeichnet." https://de.wikipedia.org/wiki/Topinambur#:~:text=Mancherorts%20in%20Baden%20wird%20Topinambur%20als%20Erdapfel%20bezeichnet https://de.wikipedia.org/wiki/Topinambur#:~:text=Mancherorts.... Topinambour would have been available in the middle ages. Confusion with potato by the modern reader is understandable, as a topinambour does look similar to a potato, and some German dialects (e.g. Swiss dialects) name potatoes "Erdapfel".

> Topinambour would have been available in the middle ages. No, Helianthus tuberosus [1] aka "topinambur" is Jerusalem artichoke which would not have been available at the time. It's a New World crop just like the potato. We're talking about a book written in 1462, before the Columbian exchange. The plant wasn't introduced to Europe until the early 17th century.
