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. Unverified) 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. Next, let's talk about the temperature at the end of milking. 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. Xiaohan thinks that scientific metrology is also good, so it is very difficult for traditional Chinese medicine to pass on.
The sprinkler is in good contact with the milk, that is, open the steam valve, and the vat moves down very slowly, and you will hear the steam of "eating"cut" with the milk (about the shear force, when we discuss the principle of milk foaming later, talk 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.
That is, no matter how much air pressure is used (in the allowable range of the boiler, personal understanding: 0.8-1.2bar), it can produce very good quality milk foam. First, establish a premise: use the 600ml medium pull vat (old-fashioned), hit a jar full of milk foam, and make the WBC standard two cups of foam thickness in 1cm cappuccino. This topic refers to the problem of foam distribution, that is, how to make the foam thickness of two cups of cappuccino consistent. Our slightly experienced operators all know that there are some tricks to achieve this, which is not difficult to master, but you must have a deep understanding of the state of the milk foam in the jar.

Manual bean grinder operation step 3: shake the handle to start grinding, pay attention to force appropriate uniform speed. No matter what kind of grinder is used, it is bound to generate heat by friction in operation. Most of the fine substances are highly volatile, the heat of grinding will increase the speed of volatilization, and mellow is lost in the air. After the coffee bean is ground, the cell wall will completely disintegrate, and the area in contact with the air will

Coffee lace is not suitable for what kind of milk is used as material-there are many different ways to make good milk foam tissue, but they all contain two stages: the first stage is to get rid of, that is, to put in steam to make the volume of milk foaming, and the second stage is to soak the foaming milk, which is to make the foamed milk into the air by means of eddies.
