2. The characteristics of the annual ring cake are that after being cut, it will appear as golden rings, hence the name of "annual ring"-the first annual ring cake was baked by Johann Christian D. Andreasschernikow (1784-1852) in Salzwedel, Germany in 1807. Baumkuchen's production method has a quaint flavor! Tracing back to its development process, ancient Greece has adopted the processing method, that is, the dough with a texture similar to bread is rolled up and baked. I believe this is Baumkuchen's previous life today!
