Thoroughly mix eggs, sugar, salt and vanilla. Slowly stir in hot milk. At once, pour into unbaked pie shell. (To avoid spills, fill at oven). Dash top with nutmeg.
Bake in very hot oven (475 degrees) for 5 minutes, then reduce to 425 degrees and bake 10 minutes longer or until knife inserted halfway between center and edge come out clean. Cool on rack. Serve cool or chilled.
