With Nestle's cups, a spoonful of coffee plus two spoons of mate (Nestle inside the spoon), I usually add a little sugar, because drinking portable bags of drink used to feel the taste of dessert good. According to personal taste, they feel good on it ~ coffee cups are generally about the same capacity, the water poured full from the mouth of the cup 1cm or so, so it is not easy to sprinkle and also show politeness

Give foreigners to drink if you do not know their tastes or coffee and mate 1:2, this is Nestlé's recommended amount

The water should be freshly boiled, the first brewing coffee, stirred and then add mate, and finally put sugar.

Square Sugar The raw material of refined granulated sugar containing 2 to 2.5% moisture is pressed into square shape by a rotating drum type square sugar briquetting molding machine, and then the molded square sugar is placed on a metal tray and dried in a drying oven to less than 0.5% moisture, cooled to room temperature and then packaged in a carton.

It is usually sold in large supermarkets.

If you don't have it, you can replace it with sugar
