A recipe from the late Kenneth Roberts.
Bake a large-size graham-cracker pie shell according to the directions on the package and let it cool. Soak the gelatin in the water, then bring it to a boil and stir it into a mixture of the egg yolks and sugar. Fold in the whipped cream and the rum, pour the mixture into the baked pieshell, and chill. Serve topped with more whipped cream: (This does seem, really, to be gilding the lily!)
