Thanks to Pat, researcher extraordinaire, who came up with the solution in this blog which is by a man (with a sense of humour) in Montana who has a small artisan coffee roastery and was given one of these items.  (click on the underlined words to access the links).

Of course I will follow the  instructions and make a cup of coffee!  And reflect on this whole adventure and be amazed and amused and - well, grateful to be taking part.
