Make milk foam and then brew espresso (Espresso). You can also brew coffee espresso first and then milk foam. The order can vary from person to person.

After making the coffee, slowly pour the foam into the freshly finished espresso. When the milk foam is fully mixed with espresso, the surface will be thick, and this is the time to start drawing flowers (usually the cup is half full). The start of the pull flower is to shake the wrist holding the flower cup from left to right, and the key point is to steadily make the wrist shake horizontally to the left and right. Please note that this action only requires the strength of the wrist, not the whole arm. When the shake is correct, the cup will begin to show white "zigzag" foam marks. Gradually move the flower cup back, and reduce the range of the shaking, finally, when the cup is closed, draw a thin line forward, draw the stem of the leaves in the cup as the end.

The first step is to understand the correct operation process of the coffee machine steam system, understand the purpose of the empty steam pipe before and after foam, and understand the importance of towels and easy cleaning in coffee making.

The second step is to learn how to use the sprinkler to touch the milk surface, the location and depth of the selected point.

Step 3 recognize the two temperatures. One is the starting and ending temperature of foaming, and the other is the temperature at which the milk foam is made. These two temperatures are very important for beginners, which is directly related to the mastery of the principle of foam. First of all, when it comes to foaming, the milk is cold at first (preferably refrigerated at 5 ℃), which can prolong the foaming time so that it can be fully foamed and delicate, and then open the steam valve to foam the milk. When foaming is consistent with our body temperature (feel neither hot nor cold), the foaming is cut off. Because our hand temperature is about 30 degrees, so I personally think that the temperature of milk foam should be between 65 and 70 degrees. Because if it is too hot, it will destroy the nutritional value of milk.

Next, let's talk about the temperature at the end of milking. In fact, there are many theoretical theories about this temperature, but it is not detailed here. We will talk about the feeling when we discuss the flavor of liquid milk in the future. I just want to talk about what the temperature feels like on the hand. When we feel this temperature with our hands (in continuous heating), it is hot, but we can stand it for two or three seconds; as soon as we feel warm, we stop heating (the back end of the heating feels very hot on the hand, but it can hold it).

In some places, thermometers are used to measure. I think this kind of teaching method is not good. Technology is something that people need to understand attentively, and it is not very good for people to improve their own skills with the help of external forces.
