What is the primary purpose of steaming milk for coffee drinks?

Steaming milk is primarily done to enhance both texture and flavor, making it an essential skill in preparing coffee drinks, particularly espresso-based ones like lattes and cappuccinos. When milk is steamed, it is heated and incorporates air, which creates microfoam. This microfoam adds a creamy texture to the drinks, making them more enjoyable and luxurious.

In addition to improving texture, steaming also contributes to the flavor of the milk by altering its sugars and proteins during the heating process, resulting in a sweeter, richer taste. This enhancement is key in balancing the bold flavors of espresso, leading to a well-rounded coffee experience.

While latte art can be a delightful byproduct of good steaming technique, it is not the primary purpose. Other options like cooling the milk or reducing lactose content do not align with the steaming process, as steaming actually increases the temperature of the milk and does not significantly change its lactose content. Hence, the enhancement of texture and flavor stands out as the primary purpose of steaming milk for coffee drinks.
