First take an empty plastic bottle. Add sugar coffee and water

Now shake it with full force until all the mixture changed into a Smoot thick frothy mixture.

You will feel that you cannot shake it more

Meanwhile boil milk

Take your serving cups and pour coffee mixture in each in equal proportion

Now pour boiled milk in cups.. pour it from a side to maintain it's proper appearance.

Decorate it as you like. I made hearts with cocoa powder
