Praktische Konditorei-Kunst was a popular early twentieth-century guide for pastry students and chefs who supplied baked goods to Konditorei, those tearooms and cafés specializing in pastry arts. The importance of this sixth edition lies in its nearly complete set of cake decoration templates and perforated parchment guides, the original supplements that rarely withstood decades of use in professional kitchens.

A well-used handwritten recipe for Pfeffernüsse—a traditional German holiday cookie—from 1892 also finds a home in Blank's collection.
