Preparation
Step 1
Make the crust: Stir together the graham cracker crumbs, butter, sugar, and salt in a bowl. Press into the bottom and up the sides of a 9-inch pie plate. Refrigerate until firm, about 30 minutes. Preheat the oven to 350°F. Bake until the crust is set and begins to turn golden brown, about 12 minutes. Let cool completely on a wire rack.
Step 2
Make the filling: Sift together the sugar, cocoa powder, cornstarch, and salt into a medium saucepan. Gradually whisk in the milk. Cook over medium-high heat, stirring constantly, until almost boiling. Reduce heat to medium; add the chocolate. Cook, stirring constantly, until the chocolate has melted and the mixture is thick, about 2 minutes. Remove from heat; whisk in the butter and vanilla until smooth. Spread the chocolate mixture over the crust. Refrigerate until cold and firm, about 1 hour.
Step 3
Make the topping: Prepare an ice-water bath; set aside. Sprinkle the gelatin over 2 tablespoons cold water in a small bowl. Let stand until soft, about 3 minutes. Whisk 1/4 cup sugar, the cornstarch, and the salt in a medium saucepan. Gradually whisk in the milk. Cook over medium-high heat, stirring constantly, until the mixture is thick and boiling, about 5 minutes. Remove from heat; stir in the gelatin mixture, and let cool completely. Stir in the vanilla and rum. Briefly place the pan in the ice-water bath to thicken slightly, if needed. Do not let it set completely. Set aside.
Step 4
In the bowl of an electric mixer fitted with the whisk attachment, beat egg whites on medium-low speed until soft peaks form. Reduce speed to low; continue beating while you make the syrup.
Step 5
Bring the remaining 1/2 cup sugar and 3 tablespoons water to a boil in a saucepan, stirring to dissolve the sugar. Brush down the sides of the pan with a wet pastry brush to prevent crystals from forming. Cook, without stirring, until the syrup registers 240°F on a candy thermometer.
Step 6
Raise the mixer speed to high, and beat the egg whites just until stiff peaks begin to form. Immediately pour the syrup into the egg whites in a slow, steady stream near the side of the bowl, avoiding the whisk (it might splatter). Beat until glossy and cooled, about 7 minutes.
Step 7
Fold the meringue mixture into the reserved gelatin mixture in 3 batches until just combined. Mound the mixture into the chocolate-filled crust. Refrigerate the pie for 2 1/2 hours or overnight before serving.
