S'mores To Feed A Crowd!

Step 1: Preheat oven to 350 degrees F.

Step 2: In a food processor process the graham crackers until fine crumbs form; transfer to a large bowl. Add 3 tablespoons sugar, butter 1/4 teaspoon salt, 1 egg white and the whole egg; stir to combine. Press mixture into the bottom of a 13 x 18 inch pan which has been coated with cooking spray. Bake at 350 for 8-10 minutes or until crust is set. Remove from oven and sprinkle chocolate in an even layer over the hot crust; spreading evenly as the chocolate melts. Cool completely in the pan on a wire rack.

Step 3: Preheat broiler to high.

Step 4: Place remaining egg whites in a large bowl and then add the vanilla, cream of tartar and remaining salt (1/8 teaspoon); beat with an electric mixer at high speed until soft peaks form.

Step 5: Combine remaining 1 cup sugar and 1/3 cup water in a saucepan; bring to a boil and cook without stirring until a candy thermometer registers 250 degrees. Gradually pour the hot syrup in a thin stream over the egg whites; beating at medium low speed and then at high speed until stiff peaks form. Spread over cooled chocolate graham crust.
