Hans: I am curious to learn more about what you are speaking of. I've done a lot of research online and thought that pumpernickel was the bread described in the article.
It's hard to learn more about it because most helpful information is in German, and as much as I wish I knew the language, I do not. If it's not too much trouble, I'd love to have an authentic recipe of both the Schwarzbrot and the Pumpernickel.
I already make the Schwarzbrot regularly, but only from info that I've been able to piece together - it turns out well, but an actual recipe would be great! And I'd love to make a real Pumpernickel, too! Thanks so much, Nancy
