Jack, I just made Zopf using the recipe on the back of the 1kg pack of Zopf flour. It rose humongously, to my surprise. Forgot to mix the egg yolk with water before painting on the top, so the top was kind of 'fake looking'.
The taste is too neutral for my liking. Can I add more salt or sugar or both, you think? And maybe some sunflower seeds? (Are the Swiss and German ancestors spinning in their graves yet?)
