Fresh Strawberry Pie

This is Dad's grandma's recipe that Grandma Lorimer always made us. This is certainly one of my favorites.

1 pie crust (already prepared)
sliced fresh strawberries (enough to fill your pie crust most of the way)

1 cup sugar
1 1/2 cups cold water
3 1/2 tablespoons cornstarch
1/4 teaspoon cinnamon
1 teaspoon butter
red food coloring

Stir sugar and cornstarch into water until they dissolve. Add cinnamon, butter, and food coloring. Heat mixture until it becomes transparent, stirring sometimes. Once it is transparent, let the mixture cool. Once cool, add sliced strawberries. Put strawberry mixture into pie shell and refridgerate. (Do not let sit for too long. Pie crust gets soggy.) Serve with whipped cream.
