Black Tea in Turkey is served in “small tulip-shaped glasses” in most of the tea parlors. Black tea is one of the most popular teas in Turkey.
The double kettle is how the Turks prepare the tea, one larger pot at the bottom and a smaller pot at the top. The larger pot holding the water as it boils, some of the water is poured over the tea leaves in the small pot that is on top. Then the rest of the boiled water is poured over the leaves, leaving a very strong bold tea. More water can be added to dilute the tea to your taste. A clump of sugar is then added to your cup. The use of milk is not used and tea without sugar is not done.
