Milk foam is the product of a fine mixture of milk and air. The way to make milk foam is to pump air into the milk. The principle is simple, but it is not a simple thing to make a cup of dense and meticulous foam. The most common problem is that too much air enters the milk, producing too thick hard foam, which floats on the surface and cannot be fully mixed with coffee, so you can't enjoy the fine texture of foam and coffee when you drink it. It is recommended that you use a steam foam machine to make milk bubbles, which will make the process easier.
