Serves 6 to 8.
Note: This was a dinner party favorite in the 1950s, but it's still suited for the family dinner table. If you prefer to use fresh broccoli, steam it in advance until done. Have cream whipped before you start the sauce. From "Southern Living Heirloom Recipe Cookbook," by the editors of Southern Living magazine.
• 1/2 c. butter
• 1/2 c. flour

Preheat oven to 450 degrees. Lightly grease a 7- by 11-inch baking dish.
Melt butter in a heavy saucepan over low heat; whisk in flour. Gradually add milk and cook, whisking constantly. Gradually stir about a quarter of the hot mixture into egg yolks; add egg yolk mixture to remaining hot mixture, stirring constantly. Stir in sherry, Worcestershire, Parmesan and salt.
