First, put the milk in a milk jar with a small, medium and large cup, then use 7g spoons to dig three spoonfuls of chocolate powder, that is 21g, and then pour them into the milk jar to fully blend with the milk, and then use a steam pipe to heat the temperature. I won't talk about it.

Finally, the effect of pouring it into the cup is to pour a drop of white milk foam along the cup wall and sprinkle chocolate powder on it when it is 7/8 minutes full.

The requirement is that the chocolate milk foam should be one centimeter as the latte!
