Notes
This recipe basically uses 1:1 ratio on all the ingredients, double the recipe to make two servings. Depending on personal preferences, decrease sugar down to 1-1.5 tbsp if you prefer less sweet coffee or try a darker roast coffee. The original recipe calls for 2 tbs of sugar. Use more sugar if you prefer a sweeter coffee.
