On the basis of Italian espresso, add a thick layer of frothy milk to make cappuccino. The quality of espresso will not be obvious under milk and foam, but it is still an important factor in determining the taste of cappuccino. Pour partially defatted milk into a pot, then use a frother to make the milk foam and aerate, and make the milk as uniform as whipped cream without burning. The coffee cup containing cappuccino should be warm, otherwise the poured milk foam will disperse. Usually, these cups can be placed on the top of the coffee machine to keep warm. Pour milk and foam on top of espresso, and naturally form a layer, just like wrapping the coffee below. Note that the brewed Italian coffee is about five minutes full, and the hot milk that has been foamed is poured to eight minutes full. Finally, according to personal preference, sprinkle a little cinnamon powder or chocolate powder, and the rest of the milk can also be poured in, so that a delicious cup of cappuccino is made.
