Why milk bubbles can't be injected into coffee-coffee into milk

After the machine has reached the correct temperature, turn on the steam switch, drain the water that will always be present in the steam pipe, and then turn off the steam switch.

Place 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 get bigger bubbles, and you have to work hard to get rid of them.

Slowly bring the nozzle to the surface of the milk. Stop just as it breaks the surface. Now that the air is sucked into the milk, you hear a typical hissing sound. If you accidentally lift the nozzle above the water, the pressurized air will blow onto the milk instead of into it, creating 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 remove them. There will be a vortex where the air blows into the milk. All bubbles on the surface are pulled into the vortex and disappear. It is still important to place the nozzle in the correct position to avoid creating new bubbles.

Now you have a glass of texture formed by tiny bubbles. Put your free hand on the cup to feel the milk temperature. As the foam rises you carefully lower the steam pipe so that it touches the milk. If you are satisfied with the amount of foam and the milk is not warm enough, lower the nozzle into the milk. Now the milk starts to swirl. This allows the milk to be heated evenly by the steam. When your hands feel a little warm, keep the nozzle below the liquid level and turn off the steam.

Swirling and pouring often still causes bubbles in your foam. A good way to get rid of these bubbles is to tap the cup hard on the bench. Don't tap too many times to avoid creating too much foam. A good way to tell if milk is "thick" enough is to rotate the cup so that the milk begins to swirl. You have to make a few cappuccinos to learn what milk should look like.

1, first with hot water warm cup, water boiled after standing for 20s.

Pour the coffee powder into the filter paper, and first penetrate the coffee powder with a small amount of hot water for about 20 seconds.

Slowly add the remaining hot water to 8 minutes full and let the coffee slowly filter into the cup.

4, the hot milk bubble, pour on hot coffee. Add sugar, chocolate powder or cinnamon powder according to personal preference.

Just boiled water temperature is too high, it will destroy the taste of coffee, so the boiling water will rest for 20 seconds and then brew, so that coffee presents the most perfect state
