This is the way I learned to make Nescafe while visiting my husband's family in Serbia. To me, this is more of a dessert coffee, because it is very sweet. (These measurements are for a standard size coffee mug)
Put the Nescafe granules in a coffee mug. How much you use will depend on how strong you like your coffee.
Add the light brown sugar.
Add just enough boiling water to cover the granules and sugar, but not too much more than that.
With an electric (or battery powered) hand-held frother, whip the sugar and Nescafe together until it gets to the consistency of cream. (This took a little practice for me to get it to foam. Just continue frothing; it will ultimately cream-up. I found that using the frother in an up & down manner to add a little air, worked best for me).
Once you get the creamy consistency, add more boiling water to fill the mug.
The creamy part will rise to the top of the mug. Do not stir. Add just a shot of milk on the top of the cream.
