Semi-automaton foam to get rid of the whole playbook listening and debating foam

We already know that dispelling milk foam is actually a dynamic process of lifting and pulling up and down the milk tank, so how can we know when the milk tank should be lifted up and when it should be pulled down? In fact, we usually judge by the sound made when we foam. Phellodendron mandshurica (Thunb.)

Silent

If there is no sound, it generally means that the liquid surface of the milk is too deep when the steam pipe is inserted. At this time, the milk is usually heated but not foaming. You should slowly pull the milk jar down until you hear the wonderful "bared" sound. In this case, steam can be used to heat a variety of liquids, and even steam pipes can be used to make scrambled eggs.

A noisy "spitting" sound.

Such a sound generally means that your foam is relatively rough, so you will find that you will soon get a large vat of foam, but obviously that kind of foam is not the delicate and lasting foam we need, they are more similar to soap bubbles. It will soon burst, and the taste is very rough. If you use this foam to make a cappuccino, then I would advise you to let others finish the cup of coffee as soon as possible, otherwise it will soon become half a cup of coffee due to the dissipation of the foam. When you hear such a sound, you should lift the milk jar slowly until you hear the sound of "bawling".

A "bared" sound with a sense of rhythm

When you are full of rhythmic "bared" sound, then you say to make a delicate and lasting foam, the point at this time is that you must follow the rise of the foam, slowly pull the milk tank in order to achieve balance in the dynamic. It takes a certain amount of practice to get rid of the foam, especially the right amount, delicate and lasting foam.
