03Place a baking sheet on the middle oven rack and preheat to 425 degrees F. Make the filling: Whisk the heavy whipping cream, sugar, flour and vanilla in a bowl. Pour into the chilled crust, dot with the butter and sprinkle the nutmeg on top. Carefully transfer the pie plate to the hot baking sheet and bake 10 minutes. Reduce the oven temperature to 350 degrees F and continue baking until the crust is golden and the filling is bubbly in spots, about 55 more minutes (the center will still jiggle slightly); cover the crust edges with foil if they're browning too quickly. Transfer to a rack and let cool completely. Serve chilled or at room temperature.
