Portuguese " Secret" Coffee - cooking recipe

Ingredients

1 teaspoon instant coffee
1 teaspoon sugar
hot water

Preparation

Into a mug, place the coffee and sugar. Mix in a couple of drops of tepid water and stir until the mixture looks like black cake dough. Keep mixing until it turns white, or yellow, then fill with boiling water.
By oxygenating the coffee, you end up with a creamy yellow drink with foam on top.
