Mary Lee Taylor hosted “the longest-running cooking program on radio” from 1933 through 1954 and was sponsored by PET Milk (you can learn more about the show and listen to some episodes here: Internet Archive: The Mary Lee Taylor Program). This recipe was clipped from a PET Milk label sometime during that period. The recipe is typed below along with a scanned copy for archives.
