How to beat foam with Steam-the principle of foam with Steam

After the machine reaches the correct temperature, turn on the steam switch, release the water that always exists in the steam pipe, and then turn off the steam switch.

Put the nozzle under the surface of the milk and turn on the steam. If you turn on the steam when the nozzle is above the liquid level, you will get larger bubbles, and it will take a lot of effort to get rid of these bubbles.

Slowly take the nozzle to the surface of the milk. Stop (stop just as it breaks the surface) just as the nozzle is about to come off the surface. Now that the air is sucked into the milk, you will hear a typical hiss. If you accidentally take the nozzle out of the water, the pressurized air will blow on top of the milk instead of into the milk, resulting in large bubbles.

At this stage, there is no doubt that you have formed small and medium-sized bubbles on the surface of the milk. Now we will try to get rid of them. There will be a whirlpool where the air blows into the milk. All the bubbles on the surface will be pulled into this whirlpool and disappear. It is still important to put the nozzle in the right place to avoid new bubbles.

Now you have a texture made of tiny bubbles. Put your empty hand on the flower cup to feel the temperature of the milk. When the foam rises, you lower the steam pipe carefully so that it touches the milk. If you are satisfied with the amount of foam and the milk is not warm enough, you can lower the nozzle into the milk. Now the milk is beginning to swirl. By doing so, the milk can be evenly heated by steam. When your hands feel a little hot, keep the nozzle below the liquid level and turn off the steam.

Whirlpool and pouring will still have bubbles in your foam most of the time. A good way to get rid of these bubbles is to tap the flower cup on the workbench. Don't knock too many times so as not to cause too much foam. A good way to judge whether the milk is thick enough is to rotate the flower cup so that the milk begins to form a whirlpool. You have to make more cappuccinos to learn what milk should look like. But here are some suggestions:
