If you use a Nestle cup, I usually add some sugar to a spoonful of coffee and two spoons of partner (spoon in Nestle), because I am used to drinking in a portable bag, and I feel that the dessert tastes good. Just feel good according to my personal taste ~ Coffee cups are almost the same in general capacity, and the water is about 1cm from the cup mouth, which is not easy to spill and also polite.
If you give it to foreigners, you don't know their taste or coffee and partner 1:2, which is the recommended amount of Nestle.
If the water is just boiled, make coffee first, stir it, then add your partner, and finally put sugar.
Cube sugar refine granulated sugar raw material with 2-2.5% wat content is pressed into cubes by a rotary drum cube briquetting machine, then that shape cubes are placed on a metal tray, the water content is dried to below 0.5% in a drying oven, and the cubes are packaged in paper boxes after being cooled to room temperature.
