Which two ingredients should be stirred together before adding milk?

The combination of espresso and syrup or sweeteners should be stirred together before adding milk because this process ensures that the flavors are evenly distributed throughout the beverage. When syrup or sweeteners are added directly to milk without first mixing them with the espresso, it can result in uneven sweetness, where some sips may taste overly sweet while others may taste too bitter. By combining the espresso with syrup or sweeteners first, you create a well-balanced flavor that complements the milk and enhances the overall coffee experience. This method is especially important in espresso-based drinks where precise flavor profiles are desired. Stirring these ingredients together creates a harmonious blend, making for a more enjoyable drink that showcases the best characteristics of both the coffee and the added flavors.
