Preheat oven to 350 degrees F. Coat a 9-inch pie pan
with cooking spray.
To prepare crust: Process 32 wafers, confectioners' sugar, oil
, milk and butter in a food processor
until finely ground. Press the mixture into the bottom and up the sides of the prepared pan, creating an even, dense crust. Bake for 12 minutes. Cool on a wire rack to room temperature, about 1 hour, pressing any puffed parts of the crust back into the pan.
To prepare filling: Meanwhile, puree raspberries, lemon juice and salt in a blender
processor until smooth. Strain through a fine-mesh sieve into a medium bowl, pressing with a rubber spatula to extract the juice; discard seeds.
Bring 1 inch of water to a slow simmer in a large saucepan. Combine egg whites, granulated sugar and cream of tartar in a 3-quart stainless-steel bowl. Beat with an electric mixer on medium speed until foamy. Set the bowl over the simmering water and continue to beat on medium speed, moving the mixer around, until the mixture is glossy and thick, about 3 1/2 minutes. Increase the speed to high, and continue beating over the simmering water until very stiff and glossy, about 3 1/2 minutes more (the eggs will be at a safe temperature, 160 degrees F, at this point). Remove from the heat (be careful of the escaping steam) and continue beating on medium speed until room temperature, 3 to 5 minutes.
Fold the raspberry puree into the meringue until combined. Pour the raspberry filling into the pie crust; crumble the remaining chocolate wafer over the top. Place the pie on a level surface in your freezer and freeze until solid, at least 6 hours. To serve, let the pie stand at room temperature until softened slightly, about 10 minutes, before slicing.
Note: Look for chocolate wafer cookies without any partially hydrogenated oils. Our two favorites were both from Newman's Own Organics: Tops & Bottoms and Chocolate Alphabet Cookies. Chocolate Snaps from
Mi-Del will also work, but the chocolate flavor isn't as rich.
Tip: To get the most volume from beaten eggs, it's best for them to be at room temperature. Either set the eggs out on the counter for 15 minutes or submerge them in their shells in a bowl of lukewarm (not hot) water for 5 minutes.
MAKE AHEAD TIP: Cover with plastic wrap and store in the freezer for up to 2 weeks.
