I just had to share this with my readers. Teresa Stannard is the director of the library in a place called Parchment, Michigan. Parchment paper was manufactured there from 1912 – 2000 at the Kalamazoo Valley Paper (KVP) Company.   The library has many samples of the papers the plant produced, but KVP was especially known for its parchment paper.   Here is a link to a scan of a 1931 KVP booklet in their collection entitled “Paper Finds Many New Uses.”   It contains several pages devoted to parchment paper cooking techniques.  You have got to check this out – as well as the other uses they describe for parchment paper! Many thanks to Teresa for sharing this!
