Donna s White Sauce

¼ cup butter

3 tablespoons all-purpose flour

1 quart heavy cream

Melt butter in a medium sauce pan over medium heat. Whisk in flour. Remove from heat and add a small amount of cream, stirring to prevent clumping. Return to low heat and add cheese. Stir until cheese melts and sauce thickens.
