   Put oven rack in middle position and preheat oven to 350u00b0F. Put chocolate in a large bowl. Bring cream just to a boil in a 1- to 1 1/2-quart heavy saucepan, then pour hot cream over chocolate. Let stand 1 minute, then gently whisk until chocolate is melted and mixture is smooth.

   Begin beating water and gelatin mixture with an electric mixer at medium speed, then carefully pour in hot syrup in a slow stream, beating (avoid beaters and side of bowl). When all of syrup is added, increase speed to high and continue beating until mixture is tripled in volume and very thick, about 5 minutes. Add vanilla and beat until combined, then immediately spoon topping onto center of pie filling; it will slowly spread to cover top of pie. Chill, uncovered, 1 hour, then cover loosely with lightly oiled plastic wrap (oiled side down) and chill 3 hours more.

Cool pie on a rack 10 minutes. Slice pie with a large heavy knife dipped in hot water and then dried with a towel before cutting each slice.
