What is the purpose of a milk pitcher in pouring?

The purpose of a milk pitcher in pouring is primarily to control the flow and angle for accurate pouring. This design allows baristas to have precision while pouring, which is essential for creating latte art and ensuring that beverages are crafted to the desired presentation and taste. The shape of the pitcher is typically designed to make it easier to pour in a stable, controlled manner, allowing the barista to create beautiful patterns with the milk on top of espresso. The ability to manipulate the angle and speed of the pour can significantly influence the overall quality and aesthetic of the drink.

The other options, while related to milk and its use, do not reflect the primary function of the milk pitcher in the context of pouring. Keeping milk cold and ensuring it doesn't spoil pertain more to storage and freshness than to the act of pouring. Frothing milk is a specific process that often involves different equipment, such as a steam wand, rather than just the pitcher used for pouring.
