South Indian filter coffee is wonderful. Here is how it is prepared. First coffee powder is placed in the upper chamber of a cylindrical metal vessel with a finely perforated base. Hot water is poured on it. Then, the water slowly filters through the powder to produce an intensely strong, undrinkable filtrate, known as ‘decoction’. This filtration takes many hours.
The coffee-maker ladles some decoction into a vessel, often a stainless steel beaker. Then, he or she fills the rest of the beaker with freshly boiled milk (With or without sugar).
If you want your coffee without sugar, ask for “sugarless”.
The coffee cup comes with a deep saucer. To cool the coffee, you pour the coffee from the beaker to the saucer and vice versa.
