Freezer Cheese Sauce - cooking recipe

Ingredients

3/4 cup all-purpose flour
1/2 teaspoon salt
1/4 teaspoon ground nutmeg
3/4 cup butter
4 cups milk
4 teaspoons beef bouillon (could use chicken or vegetable, I prefer the Better than Boullion line)
2 cups water
1 cup half-and-half
4 egg yolks, beaten
12 ounces cheddar cheese, shredded (3 cups)

Preparation

In a small bowl, combine flour, salt and nutmeg; set aside. In a heavy large saucepan, melt butter over medium heat. Gradually stir in flour mixture, milk, bullion, and water until smooth. Cook and stir until smooth and slightly thickened, about 2 minutes. Remove from heat.
In a medium bowl, stir half-and-half into egg yolks. Blend in about half of the hot sauce. Stir egg mixture into remaining sauce. Cook and stir over medium heat about 2 minutes; do not boil. Remove from heat. Stir in cheese until melted. Cool to room temperature.
Refrigerate sauce until cooled. Pour serving sizes into freezer containers with tight fitting lids. Leave 1-inch space at top of each container. Attach lids. Label with date and contents. Store in freezer. Use within 6 months.
Serving size recommend was 1 1/3 cup (meaning recipe makes 6 servings) but we have a small family and I use 1/2 to 2/3 size servings.
