The preparation of a chilled, aerated topping, similar in texture to meringue but lighter, is a common practice in specialty coffee preparation. This topping is typically achieved by blending or frothing cold milk or cream until it forms a stable, foamy consistency. An example includes adding this aerated topping to iced coffee, creating a layered beverage with distinct textural and flavor profiles.
The appeal of this preparation lies in its ability to enhance the sensory experience of cold coffee drinks. It introduces a creamy, smooth texture that contrasts with the liquid below, adding complexity to the drink’s overall mouthfeel. Furthermore, the foam can be flavored with syrups or spices, providing an additional layer of customization and flavor infusion. This technique has gained popularity due to its visual appeal and the perception of added value it brings to the beverage.
