A course in milk foaming

① first turns on the steam pipe to drain the possibly wet steam.

② adjusts the angle of the steam stick and inserts it diagonally below the liquid level of the milk in 2mm

③ turns the steam to the maximum gear, controls the depth of the steam rod, and tries not to let large bubbles occur.

④ rotates the bubbles with the milk so that the bubbles merge with the milk and make the bubbles more delicate

⑤ beat the milk to about 60 to 65 degrees and turn off the steam stick.

⑥ wiped off the milk on the steam stick with a wet cloth and let the steam out to spray the milk out of the tube.
