How should espresso be added after pouring milk in a hot macchiato?

Pouring the espresso gently on top of the milk in a hot macchiato is the correct technique to achieve the desired presentation and flavor combination. The purpose of a macchiato is to allow the rich, bold flavor of the espresso to meld with the creaminess of the milk while maintaining a distinct separation in layers. This layering technique not only enhances the visual appeal of the drink but also creates a unique tasting experience as the espresso gradually integrates with the milk.

When the espresso is poured gently on top, it allows the espresso to float on the milk without overwhelming it, preserving the integrity of both components. This method highlights the contrast between the two, enabling the drinker to savor both the espresso and milk flavors as they blend together upon drinking.

The other approaches, such as stirring quickly or blending with the milk, would disrupt this balance and diminish the clarity of the distinct flavors that a well-prepared macchiato should offer. The option mentioning "too hot to pour" does not apply, as proper method dictates an optimal temperature for pouring without compromising the drink's quality.
