Filter for coffee is shown in the picture below and we make decoction for coffee with the filter.
Coffee Filter has 4 parts s shown here.
First fix the upper compartment to the lower compartment like this.
Add 3 teaspoon freshly ground coffee powder or filter coffee powder you get in stores.
Place top chamber on it. Press it well.
Add ¾ cup hot water to it. If you want strong decoction then add ½ cup water.
After adding water close and keep it undisturbed for 20 minutes at least for the decoction to drip down fully.
It takes time as it slowly drips because of the finest holes.
Add ¼ cup decoction to a serving glass.
Add ¾ cup hot water to it. Add less water if you like your black coffee strong.
Mix it well. Add sugar if needed. Black coffee is ready!
Black coffee is ready. Serve hot!
