What is the purpose of using an aerator when foaming milk?

• A. To heat the milk faster
• B. To incorporate air into the milk for texture
• C. To keep the milk cold
• D. To improve the milk's shelf life

Answer: (B)

The primary purpose of using an aerator when foaming milk is to incorporate air into the milk for texture. When milk is steamed and aerated correctly, it creates microfoam, which enhances the texture and overall mouthfeel of the milk. This microfoam is essential for making beverages like cappuccinos and lattes, where a velvety and creamy texture is desired. The aeration process transforms the milk, allowing for an interplay between liquid and foam that adds both visual appeal and a rich experience for the drinker. In contrast, other options address aspects unrelated to foaming effects. Heating the milk faster is not the focus of using an aerator; rather, the goal is to create froth and texture. Keeping the milk cold or improving shelf life does not relate to the foaming process itself, as aerators are specifically designed for introducing air rather than managing temperature or extending longevity.
