Do any of you have any familiarity with this German ginger "stomach bread"? They are glazed, diamond shaped, two-bite gingery bread/cookie... things. My wife is remembering it fondly from a winter trip to Germany years ago. While there are a fair few recipes online, they vary about as widely as you might expect. Has anyone made these? Has anyone even heard of or eaten these? What should I look for in a good recipe?
