The production of milk foam

1. The first step is to understand the correct operation flow 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 handy cleaning in coffee making. The second step is to learn how to use the sprinkler to touch the milk noodles, the location and depth of the selected points. The third step is to 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.

2, pour the milk into the milk tank, the amount should not exceed the milk bubble pot 1 stroke 2, otherwise the milk will overflow due to expansion when making milk foam.

3, use the coffee machine steam to find the right angle to make the milk dense, the temperature is about 60 degrees, can not exceed 70 degrees, otherwise the protein structure in the milk will be destroyed.

Milk foam requirement

1 milking: the most important technology, although not very advanced, but requires a long time of practice, requires delicate and smooth milk foam, do not have large milk bubbles. 2 milking angle: it is best to milk at an angle of 45 degrees with the steam sprinkler, depending on the thickness of the foam according to the fluctuation. Only a semi-automatic coffee machine can make the best lace coffee. The oil problem of coffee also plays a key role, and directly affects the taste of a cup of coffee. A cup that is too small requires too much technical experience.
