3/4 c. granulated sugar
2 1/2 c. half and half
1/4 c. brown sugar
1/4 c. corn starch
1/2 c. butter
1 tsp. vanilla extract
9 inch lightly baked pie crust
1/8 tsp. ground cinnamon

Preheat oven to 325 degrees. In medium saucepan, combine granulated sugar, 1/8 teaspoon salt and the half and half. Bring to boiling, stirring occasionally.

Meanwhile, in another saucepan, combine brown sugar and corn starch. Gradually whisk in hot half and half mixture. Add butter; over medium heat, cook mixture, whisking constantly, 5 minutes or until boiling and thickened. Simmer 1 minute. Stir in vanilla.

Pour mixture into prepared pie crust; sprinkle with cinnamon. Bake 20 minutes or until top of pie is golden. Place on wire rack; pie filling will be very loose but will thicken on cooling. Cool completely before slicing.
