Since this recipe is simply broth thickened with roux, homemade stock yields the best results. If you don't have the time to make your own, purchase stock from gourmet stores or specialty markets. Substitute fish broth or clam juice for the chicken stock to serve with fish or seafood. If you prefer a sauce that has more body and flavor, just continue simmering it until it's slightly thicker and reduced to about one cup.
1 tablespoon unsalted butter
1 1/2 tablespoons all-purpose flour
1 3/4 cups chicken stock
1/4 teaspoon salt
1/8 teaspoon freshly ground black pepper
