Polish Style Coffee. The Poles make coffee very strong, like the Greeks. A tall flat bottomed glass has a large spoonful of grounds placed in it. Then boiling water is poured over the coffee and a little or a lot of sugar is added. My grandfather occasionally said that he liked his coffee, "As black as the Devil’s Heart and sweet as a stolen kiss." It is definitely not traditional in Poland to add either milk or cream.
Usually it is not put into a cup either, but a glass. Affectionately called "spit-coffee" by drinkers because of the reaction of anyone who unwisely gets to the sludge at the bottom. Probably favored by hackers for its high caffeine content.
