What is the process called when preparing a Pousse café?

In the context of preparing a Pousse café, the correct process involves "building." Pousse café is a layered cocktail that showcases different colored liqueurs, and creating this drink requires careful pouring techniques to maintain the distinct layers of liquid.

Building refers to the method of constructing a drink in a glass, often by adding ingredients one at a time without any mixing or shaking. In the case of a Pousse café, bartenders pour each liqueur over the back of a spoon or use other techniques to allow the liquids to settle in layers based on their density, creating a visually appealing effect. This method highlights the aesthetic aspect of bartending, where the craft involves not just mixing flavors, but also presenting them artfully.

The other processes listed, like shaking, blending, and stirring, involve mixing ingredients together in different ways, which would not be appropriate for a drink meant to display separate layers.
