Caramel Pie Iii - cooking recipe

Ingredients

1 cup white sugar
1 cup boiling water
2 tablespoons butter
5 tablespoons all-purpose flour
1/4 teaspoon salt
1/2 cup milk
3 egg yolks, beaten
1 (9 inch) pie shell, baked
3 egg whites
1/4 teaspoon cream of tartar
1/2 cup white sugar

Preparation

Preheat oven to 400 degrees F (200 degrees C.)
In a heavy iron skillet, over medium heat, stir 1 cup sugar until melted and golden brown. Reduce heat to low and mix in boiling water. Set aside.
In a heavy saucepan, melt butter. Remove from heat. Add flour and salt into butter mixing thoroughly. Stir in 1/4 milk. Return pan to stove, on low heat, and add remaining 1/4 cup milk and caramel syrup. Cook, stirring constantly, until thickened. Put egg yolks in a small bowl. Add about 1/2 of the hot mixture to egg yolks. Pour the yolk mixture back into remaining caramel mixture. Cook 1 minute and pour into baked pie shell.
Beat egg whites with cream of tartar until foamy. Add remaining 1/2 cup sugar, very slowly, beating until egg whites are stiff. Spread over filling and bake at 400 degrees for 10 minutes, or until meringue is lightly browned.
