"In this recipe three simple components come together to make a pie that is equally worthy of serving at a dinner party or a casual potluck. First an easy chocolate cookie crust is pressed into a pie plate and baked until just set. Then an intensely flavored but lightly textured chocolate mousse is piled in. Last, a sweetened whipped cream is layered on top. If you’re feeling fancy, sprinkle on some chocolate shavings. What to buy: There are only three ingredients in the mousse, so each should be fresh and high-quality. The best cookie choice for the crust is Nabisco Famous Chocolate Wafers. In a pinch you can use Oreo cookies, but scrape out the creme filling first. Game plan: Have your bowl and whisk for the egg whites immaculately clean and your cream very cold...."
