Take a cup or a glass preferably as it is easier to handle glass.
In that, take both the coffee powder and sugar together.
Add 1 tsp of water.
With a spoon or a spatula, start mixing gently.
Slowly increase the speed of beating and beat it as you do with eggs. Keep beating continuously till you have fine froth.
Now pour in boiling milk and mix well.
Transfer to two empty cups and serve hot.
Notes
* You can use an electric egg beater to ease the task of beating. Set the speed to low while beating.** I have used Bru instant here. You can use any instant coffee powder as per your choice. I have tried Nescafe classic too which tastes equally good.*** You can reduce the time of beating if you can use powdered sugar instead of crystal sugar.**** If you think the water is not enough for beating, add just one more tsp of water and not definitely more than it.
