For praline: Grease baking sheet. Heat 1/2 cup sugar and 2 tablespoons
water in heavy small saucepan over low heat, swirling pan occasionally,
until sugar dissolves. Increase heat and boil until light brown. Stir in
hazelnuts. Return mixture to boil. Immediately pour onto prepared sheet,
spreading thinly. Cool completely. Pulverize in processor or blender.

For semifreddo: Beat cream in large chilled bowl until beginning to
thicken. Add liqueur and beat just until peaks form. Beat yolks with 10
tablespoons sugar in another large bowl until pale yellow and slowly
dissolving ribbon forms when beaters are lifted. Gently fold in whipped
cream and 1/3 cup praline. Spoon into serving glasses. Freeze at least 2
hours. (Can be prepared 1 day ahead.)

Beat egg white to blend. Dip grapes in egg white, then sugar, coating well.
Let dry 30 minutes.

If semifreddo is frozen solid, let soften in refrigerator 30 minutes before
serving. Garnish with grapes and mint.
