For something more, one had to wait almost forty years, but I believe it was worth it. It was then that Kazimierz Piekarski (1893–1944), head of the Old Prints Department at the Jagiellonian Library, discovered a badly damaged sheet of paper printed with more recipes from ''Kuchmistrzostwo'' (or ''Kucharstwo'', if you wish). He removed the sheet, naturally, from the cover of a different tome, namely the 1549 edition of the Latin-language ''De Tuenda Valetudine Libri Sex'' (''Six Books on the Preservation of Health'') by the aforementioned Galen.
Piekarski examined the typefaces used both on the sheet he had found and on the pages with vinegar recipes discovered by Wolski, and then compared them with the typefaces known to be used by different Cracow printers in the first half of the 16th century. And the he came to the conclusion that the two fragments came from two different editions of the same cookbook. The sheet found at the Jagiellonian Library was printed with types used at Maciej Szarffenberg's print shop, while the two sheets discovered in Warsaw must have been printed with types employed by Hieronim Wietor (ca. 1480–1547) – rather than by Florian Ungler as Wolski had assumed. But if a hundred unsold copies were found in Mrs. Unlger's inventory, then Ungler must have also printed his own edition of the same cookbook, although not a single copy of that edition has survived to our times.<ref>{{Cyt
