White Chocolate Mousse and Raspberry Parfaits

I am not sure who this recipe belongs to - I found it in a magazine a while back and it was very good.
Serve with homemade chocolate truffles. (see recipe on earlier date).

White Chocolate Mousse and Raspberry Parfaits:

For the Raspberry Sauce:
2 (10-ounce) packages frozen raspberries in syrup
Juice of 1/2 lemon
1/4 cup granulated sugar
2 tablespoons cornstarch
1/2 cup cold water
1 tablespoon Grand Marnier or other liqueur (optional)

For the Mousse:
1 teaspoon unflavored gelatin
1/4 cup water
1/4 cup milk
5 ounces good quality white chocolate, broken up into small pieces
1 1/2 cups heavy whipping cream

Instructions:
For the Raspberry Sauce:
Combine undrained berries and lemon juice in processor or blender; puree. Strain, pressing with back of spoon. Add sugar, cornstarch, water and liqueur; blend well. Place in saucepan over medium heat; bring to boil, stirring frequently. Reduce heat and continue stirring 1 minute. Remove from heat and allow to cool until ready to use.

For the Mousse:
In a glass measuring cup, sprinkle gelatin over cold water and allow mixture to soften for 1 minute to 2 minutes. Cook on high (100 percent power) for 20 seconds to 40 seconds and allow to stand for 2 minutes, or until granules are completely dissolved. (Alternatively, place cup in a bowl of hot water and stir until completely dissolved.)

In a small saucepan, bring milk to the simmering point. Remove from heat and add white chocolate. Stir occasionally until chocolate is melted and mixture is smooth. Blend gelatin into chocolate mixture and refrigerate until slightly thickened but not gelled, about 10 minutes.

Whip cream until stiff and peaks hold their shape. Fold white chocolate mixture into whipped cream.

To Assemble Parfaits:
Beginning with raspberry sauce, alternate layers of mousse with raspberry sauce into four tall parfait glasses. Refrigerate one to two hours.

To serve, garnish with partially frozen whole berries, or fresh if available.
Since all Valentine Desserts need to include chocoate - serve with chocolate truffles (recipe on prior date).
