Sour Cream-Coconut Cream Pie recipe

2 1/2 cups water
1/2 cup regular grits
1 cup granulated sugar
2 tablespoons butter or margarine
2 large eggs, beaten
1 1/2 cups flaked coconut
1/2 cup sour cream
1 chocolate-graham cracker crust
Sweetened whipped cream
Maraschino cherries

Bring water to a boil in a medium-size saucepan; stir in grits. Cover, reduce heat, and simmer 15 minutes, stirring occasionally. Remove from heat, and stir in sugar and butter. Gradually stir about one-fourth of hot mixture into eggs; add to remaining hot mixture, stirring constantly. Cook over low heat until mixture thickens and reaches 160 degrees F (about 8 minutes). Remove from heat, and stir in coconut and sour cream. Spoon mixture into prepared crust; cover and chill. Garnish with sweetened whipped cream and maraschino cherries before serving.
