Mornay sauce ingredients in a pan

    Whether you are making macaroni and cheese, croque-monsieur, or a vegetable gratin, using locally sourced Idaho ingredients in your Mornay sauce can add a touch of regional flavor and quality to your dish. Idaho is known for its high-quality and nutritious dairy and flour products, and using locally sourced milk and cheese can make a big difference in the flavor and quality of Mornay sauce. This classic French sauce is rich, creamy, and versatile. It is made with a combination of béchamel sauce and cheese, and can be used as a base for a wide range of dishes. However, what makes this sauce even more special is when it is made with local Idaho ingredients.
