Before assembling the coffee filter check whether there are any clogged pores in the filter. If not you can assemble the filter and proceed. If you notice any clogged pores, just show the pores of the filter over a low flame for 2 minutes and then proceed.
First add a layer of sugar(¼ tsp), then add the coffee powder, then place the umbrella attachment of the filter.
Now slowly pour the hot water over the umbrella attachment and close with the lid.
Leave the filter undisturbed for at least 15 minutes.
During this time, you can start boiling the milk. The milk should be boiling hot while adding to the decoction.
After 15 minutes, check whether all the water has been absorbed by the coffee powder. If not wait for a few minutes.
Then transfer the collected decoction and sugar to a glass. Add milk slowly.
Mix and froth everything together by pouring back and forth using two glasses for a better taste and serve.
Coffee is an acquired taste and hence you can see how the strength of the brewed coffee suits you. You can increase or decrease the decoction added to the milk to your preference.
