Smoked Sausages With Mustard Sauce - cooking recipe

Ingredients

1 cup half-and-half, divided
1/2 cup sugar
3 tablespoons dry mustard
1/2 teaspoon salt
2 tablespoons all-purpose flour
2 egg yolks
1/4 cup vinegar
2 (5 ounce) packages cocktail smoked sausage links, heated

Preparation

Add 3/4 cup half-and-half to a small saucepan; place over low heat, stirring occasionally, until bubbly.
In a bowl, combine the next 5 ingredients with the remaining half-and-half, stir to mix well.
Gradually add heated half-and-half, and mix well.
Return mixture to saucepan; cook on low, stirring constantly until smooth and thickened.
Remove sauce from heat and gradually stir in vinegar.
Serve with sausages (I have guessed at the amount of sausages needed; the original recipe did not specify).
