Strange Coffee Mixtures
The doctors were loath to let coffee escape from the mysteries of the pharmacopœia and become "a simple and refreshing beverage" that any one might obtain for a penny in the coffee houses, or, if preferred, might prepare at home. In this they were aided and abetted by many well-meaning but misguided persons (some of them men of considerable intelligence) who seemed possessed of the idea that the coffee drink was an unpleasant medicine that needed something to take away its curse, or else that it required a complex method of preparation. Witness "Judge" Walter Rumsey's Electuary of Cophy, which appeared in 1657 in connection with a curious work of his called Organon Salutis: an instrument to cleanse the stomach.[73] The instrument itself was a flexible whale-bone, two or three feet long, with a small linen or silk button at the end, and was designed to be introduced into the stomach to produce the effect of an emetic. The electuary of coffee was to be taken by the patient before and after using the instrument, which the "judge" called his Provang. And this was the "judge's" "new and superior way of preparing coffee" as found in his prescription for making electuary of cophy:
Take equal quantity of Butter and Sallet-oyle, melt them well together, but not boyle them: Then stirre them well that they may incorporate together: Then melt therewith three times as much Honey, and stirre it well together: Then add thereunto powder of Turkish Cophie, to make it a thick Electuary.
A little consideration will convince any one that the electuary was most likely to achieve the purpose for which it was recommended.
