White Sauce

1 1/2 tbsp butter
1 1/2 tbsp flour
1 cup liquid (broth, milk, or equal parts)

In heavy saucepan, melt butter over low heat. Blend in flour a little at a time, stirring constantly with a wooden spoon until butter and flour bubble. Cook for 2 minutes, still stirring, until mixture is smooth. Remove from heat and set aside for a minute until bubbling has stopped. Add liquid and beat vigorously with a wire whisk until sauce is completely blended and without lumps. Return to moderate heat and stir with whisk until sauce comes to a boil. Simmer for 1 minute and cover until read to serve.``
