The Madras filter coffee is nearly an institution - one that most South Indians cannot do without. The wafting aroma of freshly brewed filter coffee heralds the new day in most South Indian homes. The coffee filter can be found in the most South Indian kitchens, occupying a place of pride.
The picture shows what a south Indian coffee filter typically looks like. A lower chamber that catches the filtered coffee, the upper chamber where the coffee powder/ grounds are spooned into and boiling water is poured, the plunger which is put into the upper portion after the coffee but before the water is poured in, and the lid.
Usually the coffee filter is set up, with coffee powder and boiling water, last thing at night, so the decoction is ready for coffee in the morning. The extra decoction can be refrigerated for the day.
