How to make a cup of milk foam bar! Are you ready?

In order to successfully make a cup of espresso, in addition to the successful extraction of espresso, another important prerequisite is foam.

But exactly how to hit the milk foam? And what points should we pay attention to when making milk foam?

Specific steps?

This is actually a perceptual process, and we need to use our senses to judge the specific degree of milk.

Our hands are thermometers, our eyes help observe the rotation of milk in the tank, and our ears listen to the sound of milk as it rotates.

Before dispelling the milk, you should turn on the steam button in advance to remove the residual milk and water.

In the process, be sure to turn on the steam button after the steam stick is submerged into the milk to avoid splashing the milk in four places. In addition, the steam pressure should also be maintained at a certain level. If the coffee machine is equipped with a pressure meter, the degree should be about 1.1bar (bar, pressure unit).

To rotate the steam button in place at once, place the steam pipe in the center of the steel cup, tilting 45 degrees to the upper right near the edge of the cup, with a depth of about 1 cm.

Turn on the steam pipe, move the steel cup down slowly, and roll the milk up and down and slowly let the volume expand.

When the foam expands to eight minutes full, move the steam pipe obliquely to the right side of the center point of the steel cup near the edge of the steel cup, so that the milk bubble rolls in a vortex way. Control the angle and depth of the steel cup to involve the thicker milk foam and stop beating to the desired temperature.

Then, when the milk tank is slowly pushed up and tilted, it usually makes a deep "rumbling sound" and continues to dispose of the milk at the same angle.

When the volume of the milk starts to expand, you need to move the vat down a little bit. When it is almost nine minutes full or when your hands can no longer stand the temperature at the bottom of the vat, the milk has been sent away.

The temperature of the milk should be 60 ℃. At this time, the sound of milk should be a deeper "hum".

Last, the editor shares some key points:

1. The best storage temperature for milk is about 4 degrees Celsius.

two。 If enough milk is added to the tank, the amount of milk should reach 1 pound 2 of the volume of the tank.

3. The standard volume of milk after discarding is: milk from a 300ml tank should be able to make a cup of coffee; milk from a 600ml tank should be able to make two cups of coffee.

4. Each time you only dispense the milk before making the coffee, do not prepare it in advance.
