How is the milk foam made? Of course, milk foam, there is milk can have milk foam! Pay attention to the selection of materials. To make a good foam, you should first choose milk with high milk fat. Nestle's pure milk or whole milk with milk 3 or more is recommended at present. Because the conditions are different in different places, even the same products will be different. For example, XX's milk products in Shanghai are quite easy to foam. However, the products in Sichuan can not be played satisfactorily. Therefore, different regions, times and batches should be considered in each selection of materials.

The problem of the milk itself is solved, and then there is the problem of temperature. the first is the preparation temperature, what is the preparation temperature. we can understand it as the optimum temperature before frothing. We know that the milk is the most suitable when the milk is 70 degrees. The longer the foaming process from milk to foam is, the easier it is to fall into love, so frozen (rather than frozen) milk is assumed to be minus 5 degrees to 65 degrees. It is longer than that from room temperature to 65 degrees Celsius, and this period of time can make the milk fully foam. please note that the temperature mentioned above is 65 and 70, not the densest temperature. because the foam below 65 degrees is also relatively "water", not smooth enough, the "survival" time is short, aroma and taste are lacking. While the temperature is too high, the nutritional content of milk is destroyed too much, it is popular to say that "milk is killed", and too much milk foam will affect the effect of flower drawing and lose the fresh aroma of milk and imperfect fusion with coffee, resulting in poor taste.

The following is the process of starting to foam, suing for steam blowing. (everyone knows how to use the foam machine! )

Because the steam sprinkler has 5 holes (maybe 4?) And 2 holes, so the playing method is also different. The following is a 5-hole sprinkler, pull flower small steel cup as an example: (5-hole steam is scattered, so in order to make milk foaming evenly, meticulous gesture guidance is needed.

Pour the milk to the lower edge of the inner mouth groove (about 1 inch 2)

Drain the water from the steam pipe (wrap the vent with a veil, don't burn yourself)

Pull out the nozzle, tilt the steel cup and make the nozzle and the milk level at an angle of about 45 UV 60 degrees. The nozzle can just reach into the liquid level, do not go deep into it directly.

In the first stage, turn on the steam so that the steam ejects the milk and starts to spin.

In the second stage, after the milk is rotated, the amount of steam is increased, and the steel cup begins to be filled slowly, so that the spray hole moves toward the center of the cup and gradually goes deep into the bottom of the cup.

In the third stage, keep the position, turn the steam to the maximum, move the steel cup up and down slightly so that the upper and lower part of the milk is heated and foamed full. turn off the steam until the right temperature.

In the fourth stage, shake up and down to shake out large bubbles and scrape them off, shake them well and stand by.

The whole process should be meticulous and stable, and there should not be a shrill "wheezing" sound like steam. With regard to temperature measurement, thermometers are now more popular and can be used by everyone. My master requires to touch the steel cup wall to measure the temperature; you can first measure and then remember the temperature with your hands.

Wrap the spray hole with a wet cloth after foam, spray steam twice and wipe the nozzle to keep it clean.
