Final answer:
When serving a protein with a sauce, a ladle spoon should be used as it's designed for serving liquid or semi-liquid foods. Other spoons like slotted, serving, or tasting spoons aren't ideal for sauces.
Step-by-step explanation:
When serving a protein with a sauce, a ladle spoon should be used. Implements such as ladles are specifically designed for serving liquid or semi-liquid foods like soups, stews, and sauces. Using a ladle ensures that the sauce can be easily and neatly transferred to the plate without spilling or dripping. In contrast to other types of spoons, a ladle typically has a long handle and a deep, bowl-like cup. This design allows it to hold a substantial amount of liquid, thus making the task of saucing a dish more efficient and presentable. It is larger than a regular eating spoon but smaller than a ladle. A serving spoon typically has a long handle and a deep, slightly rounded bowl.
