I am not sure if you know this, but I grew up in the GDR, behind the Iron Curtain so to speak. It were brief 5 years but a culture doesn’t simply disappear, it changes slowly. A lot of things from the GDR culture is gone, although it has seen a revival with so called GDR stores. Anyway, the point is, as any culture, we had certain recipes in the GDR that were and still are quite unique.
