Put 3 Tbsp of coffee powder in the upper cup of coffee filter. Fix it on the top of the lower container gently, so that the powder will settle evenly.
Bring water to rolling boil and pour it over the coffee powder. Close it with lid and leave it undisturbed for 10-15 minutes.
The coffee decoction will get collected in the lower container.
Boil milk and simmer for a few minutes stirring continuously. Pour needed decoction in a cup and add milk and sugar to taste.
If you want it strong, add more decoction, if you prefer mild coffee, add less decoction.
Serve hot and frothy in tumbler and enjoy the aroma and taste of south Indian filter coffee.
