der Stollen
Wow, what a name for a pastry. Stollen. Katchung. Sounds uber German. And it’s actually not only the name for a cake, it’s also what mining tunnels are called. How do these two things connect? Well, the origin of Stollen is actually a word we all know really well: stellen (to put). A Stollen originally had the idea of “thing that stands/makes stand” and before it was used for the mining tunnel itself, Stollen was the word for the rough, wooden posts and lumps that were used in mining.
