What ingredient is used to season the milk in the Mornay Sauce?

In Mornay Sauce, the flavor and depth of the sauce are enhanced by seasoning the milk with a combination of salt, pepper, and nutmeg. Each of these ingredients contributes to the overall flavor profile of the sauce.

Salt is fundamental in balancing the flavors and enhancing the overall taste of the sauce. Pepper adds a subtle spiciness that complements the creaminess of the milk and cheese. Nutmeg provides a warm, aromatic note that is particularly characteristic of béchamel-based sauces like Mornay.

The practice of seasoning the milk with these spices not only elevates the flavor but also ensures that the sauce harmonizes well with the cheese added later, resulting in a rich, delicious final product. Thus, using all three ingredients creates a well-rounded seasoning strategy for Mornay Sauce, making "all of the above" the correct choice.
