I've heard it said that "Coffee should be black as hell, strong as death and as sweet as love". I think they must have had Turkish coffee in mind!
First you need a Ibrik (Turkish coffee pot). They are very easy to find online if they aren't available locally and they come in many sizes. Next is the coffee, you want Arabica beans ground to a powder consistency. Again, easy to get online of not locally.
Measure the amount of cold water you will need in one of the cups that you will be serving the coffee in.
Place your pot of water on the stove and turn the heat to medium-high (just until the water heats up).
Add sugar to taste and add the cardamom. Do not stir it yet, Let the water warm up little bit as above.
Add about 1-2 heaping tea spoons (or 1 tablespoon) of coffee per demitasse cup (3 oz). Do not stir it yet. Just let the coffee "float" on the surface because if you stir it now you might cause it to clump up.
When the coffee starts to sink into the water and the water is warm enough to dissolve your sugar, stir it several times and then turn down the heat to low. You should stir it several times, up until your brew starts to foam (you can also vigorously move your spoon side to side to encourage to start the foaming).
When you see the bubble "ring" forming on the surface, turn down the heat a little bit more or move your pot away from the heat source. Pay attention to the bubbles that are forming at this stage. Bubbles should be very small in size.
From this point on watch your coffee carefully. Do not let the temperature get hot enough to start boiling. (NEVER LET IT BOIL - many instructions on how to make Turkish coffee use the term "boiling" but this is totally inaccurate) The key idea here is to let the coffee build a thick froth and that occurs approximately around 158 F or 70 C (i.e., much cooler than the boiling point of water which is 212 F or 100 C at standard pressure. If your brew comes to a boil, you will not have any foam because it will simply evaporate!).
Keep it at the "foaming" stage as long as you can without letting it come to a boil. You might even gently stir your brew a little bit at this stage. The more froth, the better it will taste. Also your coffee must be fresh or it will not foam as well. If your brew gets too hot and begins to "rise", then move it away from the heat or just turn it down. You are almost done.
Repeat this process until your foam has "raised" and "cooled" at the most couple of times (NOT 3-4 times like some instructions. Even once is enough). Then pour in to your cups (quickly at first to get out the foam, then slowly) while making sure that each cup has equal amount of foam! If you are serving several cups then you might be better off spooning the foam into each cup.
Turkish coffee is always served with a glass of water. You drink water first to cleanse your pallet!
Wait about half a minute or so to let the grinds settle to the bottom of your cup.
Find a comfortable spot in which to savor your delicious coffee and remember, drink this Turkish treat..sip by sip.
