What distinguishes a cold foam topping?

A cold foam topping is characterized by its light and aerated texture, specifically designed for cold beverages. This particular foam is created using cold milk, which is frothed to achieve a creamy consistency that can sit beautifully atop a variety of iced drinks, enhancing both the presentation and the mouthfeel. Cold foam serves to complement the flavors of the beverage beneath it, often providing a subtle sweetness and creaminess without being overwhelming.

The method of preparing cold foam involves using a technique that introduces air into the milk, resulting in a delicate foam that contrasts with denser toppings like whipped cream. This distinction allows baristas to create a unique texture and experience for customers seeking refreshing cold beverages. The cooling quality of the foam is important, as it maintains the overall temperature of the drink compared to toppings intended for hot beverages.

In summary, the defining feature of cold foam is its light, airy consistency, perfected for cold drinks, making option B the correct response.
