how is it prepared?

First, you boil the water in a <a href="http://en.wikipedia.org/wiki/Cezve">dzezva, which is essentially just a copper pot</a>, and add sugar if you want. [size=10pt](Typically one small spoon of sugar for one cup, maybe half a spoon)[/size].
Then you take the dzezva off the heat, let the water rest for 10 or so seconds, then add in the coffee.
[size=12pt]The ratio I use is 1 gram of coffee for 10 grams of water[/size], so it works out that for one cup, you want one heaped teaspoon of coffee.
You then stir the coffee in for a bit (not on the heat).

You put the pot back onto the source of heat and let the coffee brew for a minute of so.
The aim is to not let the coffee boil, for even if it boils for a second, it'll taste sour.
You're trying to let the coffee form tiny, tiny bubbles, and the "krema" should build up on the top.
Then you're ready; you take off the dzezva from the heat source, and let it sit for a minute or so, so the coffee grounds settle at the bottom, then you pour the coffee.

Again, let the coffee sit in your cup for about a minute before you start drinking.
