Sugar seems to have been introduced into coffee in Cairo about 1625. Veslingius records that the coffee drinkers in Cairo's three thousand coffee houses "did begin to put sugar in their coffee to correct the bitterness of it", and that "others made sugar plums of the coffee berries". This coffee confection later appeared in Paris, and about the same time (1700) at Montpellier was introduced a coffee water, "a sort of rosa-folis of an agreeable scent that has somewhat of the smell of coffee roasted." These novelties, however, were designed to please only "the most nice lovers of coffee"; for ennui and boredom demanded new sensations then as now.
Boiling continued the favorite method of preparing the beverage until well into the eighteenth century. Meanwhile, we learn from English references that it was the custom to buy the beans of apothecaries, to dry them in an oven, or to roast them in an old pudding dish or frying pan before pounding them to a powder with mortar and pestle, to force the powder through a lawn sieve, and then to boil it with spring water for a quarter of an hour. The following recipe from a rare book published in London, 1662, details the manner of making coffee in the seventeenth century:
Coffee Making in 1662
To make the drink that is now much used called coffee.
The coffee-berries are to be bought at any Druggist, about three shillings the pound; take what quantity you please, and over a charcoal fire, in an old pudding-pan or frying-pan, keep them always stirring until they be quite black, and when you crack one with your teeth that it is black within as it is without; yet if you exceed, then do you waste the Oyl, which only makes the drink; and if less, then will it not deliver its Oyl, which must make the drink; and if you should continue fire till it be white, it will then make no coffee, but only give you its salt. The Berry prepared as above, beaten and forced through a Lawn Sive, is then fit for use.
Take clean water, and boil one-third of it away what quantity soever it be, and it is fit for use. Take one quart of this prepared Water, put in it one ounce of your prepared coffee, and boil it gently one-quarter of an hour, and it is fit for your use; drink one-quarter of a pint as hot as you can sip it.
In England, about this time, the coffee drink was not infrequently mixed with sugar candy, and even with mustard. In the coffee houses, however, it was usually served black, without sugar or milk.
About 1660, Nieuhoff, the Dutch ambassador to China, was the first to make a trial of coffee with milk in imitation of tea with milk. In 1685, Sieur Monin, a celebrated doctor of Grenoble, France, first recommended café au lait as a medicine. He prepared it thus: Place on the fire a bowl of milk. When it begins to rise, throw in to it a bowl of powdered coffee, a bowl of moist sugar, and let it boil for some time.
We read that in 1669 "coffee in France was a hot black decoction of muddy grounds thickened with syrup."
Angelo Rambaldi in his Ambrosia Arabica thus describes coffee making in Italy and other European countries in 1691:
