To make the whipped apricot souffle:
-
31
Put the apricots and 1 cup of water in a small heavy saucepan, cover, and bring to a boil.
-
32
Simmer 20 to 25 minutes or until the apricots are very soft and all but 1 or 2 tablespoon of the water has been absorbed.
-
33
Remove from the heat and add 1/2 cup confectioners' sugar.
-
34
Whip with a fork until the apricots are very smooth.
-
35
You should have approximately 1/2 cup of puree.
-
36
Put 1 tablespoon cold water in a small heat-proof glass dish and sprinkle the gelatin over the top.
-
37
Let stand for 5 minutes without stirring.
-
38
Place the dish in a skillet filled with 1/2 inch of boiling water.
-
39
Stir the mixture until the gelatin is dissolved and the mixture is clear.

40
Stir it into the apricot puree.
-
41
Set aside to cool to tepid.
-
42
Beat the cream in a small chilled bowl of an electric mixer.
-

As it begins to thicken, add 1/4 cup confectioners' sugar gradually.
-
44
Beat until soft peaks form.
-
45
Remove from the mixer and fold in the tepid puree and the Grand Marnier by hand.
-
46
To assemble:
-
47
Carefully unroll the cake, but not completely flat; the edge closest to you should remain curled.
-
48
Spoon the filling under the curled edge first, then spread it over the rest of the cake evenly with a metal spatula, leaving a 1-inch border on the far side.
-
49
To roll the cake, tuck the curled edge under and continue rolling.
-
50
Place seam side down on a wooden breadboard or oblong platter.
-
51
Cover loosely with foil and refrigerate until half-hour before serving.
-
52
Dust the top with confectioners' sugar just before serving.
