What is the primary function of a liquid measuring cup?

The primary function of a liquid measuring cup is to measure liquid ingredients. These cups are specifically designed with features such as a spout for easy pouring and clear markings indicating different measurements, which allow for precise measurement of liquids like water, milk, oil, and other fluids used in cooking and baking. This is important because achieving the right proportions of ingredients, particularly liquids, is crucial in many recipes to ensure proper texture, flavor, and overall success of the dish.

While whipping or aerating ingredients and measuring solid ingredients are important tasks in cooking and baking, they do not pertain to the primary design and purpose of a liquid measuring cup. Serving beverages also falls outside of the primary function, as this is more related to the use of containers specifically designed for that purpose rather than measuring.
