For Crust:

vegetable oil. Finely grind first 4 ingredients in processor. Add egg white
and vanilla and blend until mixture almost forms balls. Press onto bottom
(not up sides) of prepared pan, using wet finger-tips as aid. Bake until
crust looks dry and feels firm, about 14 minutes. Cool.

ocassionally. Add chocolate and whisk until smooth. Set aside.

Bring first 3 ingredients to simmer in heavy large saucepan. Reduce heat to
low. Add white chocolate and whisk until smooth. Remove from heat and whisk
in sour cream. Pour 1/2 cup of mixture into small bowl; add butter to
mixture in small bowl and whisk until smooth. Set aside for garnish.

Drop dark chocolate filling and remaining white chocolate filling
alternately by 1/4 cupfuls onto crust. Swirl fillings together using tip of
knife. Freeze until firm, about 1 hour.

Freeze reserved 1/2 cup white chocolate filling until firm enough to pipe,
stirring occasionally, about 5 minutes. Lift tart from pan using foil sides
as aid. Peel down foil sides. Turn tart on side and carefully peel foil off
bottom of tart. Place tart on platter. Spoon reserved white chocolate
filling into pastry bag fitted with medium star tip. Pipe white chocolate
mixture around edge of tart. Garnish with almonds. (Can be prepared 1 week
