Know a dead angle between a foam-drawing jar and the steam tube of a coffee machine. After watching a lot of domestic and foreign baristas beating milk foam, coupled with their own constant attempts, I found that playing milk foam has a dead angle, just like playing video games, some dead corners can not hit you, but you can hit others. This angle is very troublesome to say in words, probably because the nozzle of the flower jar must be raised, and the cylinder body should tilt the sprinkler in contact with the milk surface according to the rotation direction of the milk bubble, that is, open the steam valve, and then the flower jar will move down very slowly. You will hear the steam of "eating"cut" with the milk (about the shear force, when discussing the principle of milk foaming later, chat slowly!) The sound made is commonly known as "the sound of air intake". The sound of air intake to human body temperature can no longer appear, otherwise, there will be a lot of coarse foam on the surface. At this point, move the flower jar up a little bit (just a little bit, which is important, which is understood by many people as moving up continuously, which is very wrong), and let the steam sprinkler leave the cutting surface so that the sound of "eating" can not be heard. At this time, by adjusting the angle of the vat, remember that it is the angle, not the position of the sprinkler and the surface (very small angle adjustment), find the vortex, pull the coarse foam off the surface in the foaming stage, and continue until the temperature reaches the hot temperature.

The amount of milk added is about 2 pound 5 is enough, do not hit the highest when milking, keep the speed of the state to hit more than ten times is enough, more and more will be more and more dry. Then use a spoon to scrape off the upper layer of about 2-3cm of coarse milk foam and pull it against the flower cup several times. After pulling, tap a few times on the table, then foam in the cup, shaking the cup clockwise or counterclockwise until it is poured into the coffee. Because once you stop, it will be divided into upper and lower levels. The common problem of hand-beating milk foam is that it is relatively dry, and milk and foam are separated. It is said that the double-layer milking effect will be finer but drier than the single-layer milking effect. It has not been verified. The first step: first do fast low hit, hit until there is obvious resistance and continuous feeling; then do medium hit, also hit obvious resistance and continuous feeling; finally do high hit, hit as a whole have resistance and continuous feeling. Tip: pay attention to the height of the twitch.

Step 2: repeat the first step. In this way, the process of manual milking is completed. If you want your foam not to be too thick, to have a certain sense of flow, just take the first step. Pulling out the piston vertically after foam is helpful to drive out a lot of coarse bubbles. (since no pictures have been downloaded, I don't know the specific samples of the author's low, medium and high hits.) heat the milk (milk that can be foamed and kept, recommended Nestl é) to a temperature that is hot (60 to 70 degrees) but can hold. What kind of heating method is used is not important, the key is to reach this temperature (why this temperature should be reached will be discussed later). The heating method used in the store that I have instructed is the microwave oven. at first, it is slowly trying to find out how long it takes to heat the milk to the target temperature with a big fire, and then just put the milk in and heat it at the time after the test. it's very convenient and very fast.
