Preheat oven to 425 degrees.
In medium bowl, whisk together cream, half-and-half, sugar and flour. Pour into pie shell. Dot top evenly with butter and sprinkle with nutmeg. Bake in preheated oven 15 minutes.
Remove pie from oven. Reduce heat to 350 degrees. Wrap edges of crust with aluminum foil (or use pie shield) to prevent burning, return pie to oven and bake 45 minutes more. Let cool on rack; pie will set upon standing. Serve at room temperature.
Makes 1 pie, 8 to 10 servings.
