How to control the steam-pump type and steam type of coffee machine

About the steam in the coffee machine:

1. 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.

two。 Put the nozzle below 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.

3. 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.

4. 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 important to put the nozzle in the right place to avoid new bubbles.

5. 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.

Start a milk whirlpool and pour in:

There are still bubbles in your foam a lot of times. 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.

Some tips to see if the foam is good enough:

You can also tilt the flower cup to see how thick the milk is in the outlet. Look at the following example:

Milk should not be too thick, because if it is too thick, it will not mix well with coffee.

Milk should look like you're pouring yogurt (it may sound like a strange metaphor, but it is)

Pour the milk slowly. If it looks easy to flow, just wait a few seconds. By waiting for the air that has been blown into the milk to rise to the surface, the milk can be layered and the foam floats on it. It's like what happens after the black beer is poured out. In order to get the correct cream properties, you now need to blow the milk out of the whirlpool to mix it. You may get a nice cappuccino by doing this, but it may not be two.
