What should you do after adding espresso in an Iced Latte?

After adding espresso in an Iced Latte, the next step is to add cold milk. This is essential because the cold milk helps to cool down the espresso and blend the rich coffee flavor with the milk, creating a balanced and creamy drink. The layering of flavors is an important aspect of making an Iced Latte, and adding cold milk next ensures that it mixes well with the espresso, resulting in a smooth and enjoyable beverage.

While other actions like stirring, adding sugar or flavor, or filling with ice can be part of the preparation process, they come after the milk is added. Cold milk is what forms the base of the drink, so it's important to maintain the sequence of preparation for the best flavor and texture.
