Add coffee powder to the top compartment of the filter and spread it evenly using your fingers or a spoon. Sprinkle ¼ teaspoon of granulated sugar over the coffee. This step adds a slight caramelization.
Press the coffee powder gently with the plunger (umbrella-shaped attachment). Do not press too hard otherwise the coffee powder with fall from the pores to the lower compartment.
Top with warm water (not boiling hot) until the filter is almost full. Cover with the lid and keep the filter on the counter to let the coffee percolate.
It will take 3-4 hours for the coffee to percolate nicely and create a thick decoction. You can use the decoction after 15-20 minutes also but it will not be very thick.
Add 2 tbsp decoction in a tumbler. You can use regular coffee mugs if a tumbler is not available.
Top with boiling hot milk.
Add sugar to your taste and mix by pulling the coffee between the davara and tumbler a few times. You can skip the pulling process and just mix the sugar using a spoon. Serve immediately.
