To make Semifreddo: Prepare a Pullman Loaf Pan, 9 x 4-Inch with Parchment paper. Place in the freezer. Also freeze the serving platter. These can also be made in eight 6-ounce molds to make individual desserts.
To make the sorbet: Blend all of the ingredients, adding enough simple syrup so the egg floats, refrigerate until cold and freeze as directed here.
Once the sorbet is frozen, spoon it into the prepared pan and spread it evenly. Tap the pan several times to make sure it is settled into the pan evenly. Freeze for at least an hour before layering on the mousse.
To make the Frozen Mousse: Using a stand mixer fitted with the whip attachment, whip the heavy cream, creme fraiche, Grand Marnier, and orange blossom water until the mixture holds soft peaks. Set aside.
In a small saucepan over medium heat, combine the honey, corn syrup, and sugar. Cook without stirring until the mixture reaches 248°F on a candy thermometer.
Meanwhile, when the sugar reaches 238°F, in the bowl of a stand mixer, fitted with the whip attachment, whip the egg whites until they hold medium peaks. When the honey syrup reaches 248°F, reduce the speed of the mixer to low and drizzle the hot syrup into the whites. Increase the mixer speed to high and whip until the mixture is cool, about 5 minutes.
Fold 1/3 of the cream into the egg whites. Fold the remaining whipped cream into the whites.
Spoon the mixture into the prepared pan, over the sorbet. Tap the pan gently on the counter to make sure the mousse is even. Use an offset spatula to smooth the top flat. Freeze for at least 6 hours.
To Assemble the Semifreddo: Invert the sorbet/mousse onto a frozen serving dish. Return to the freezer while you make the meringue.
To make the Meringue: Bring about an inch of water in a saucepan to a simmer. Combine the egg whites, sugar, salt and rosemary in the metal bowl of a stand mixer. Place the bowl over the simmering water and stir the egg mixture with a rubber spatula until it is hot and all of the sugar has dissolved about 5 minutes. Remove from heat, strain the rosemary out, return the egg mixture to the bowl and place it onto the stand mixer, fitted with a whisk attachment. Beat on high speed until very thick, glossy, stiff peaks when you lift the beater, and cool to the touch, about 10 minutes. Fold in the orange zest.
Spoon the meringue over the Blood Orange Sorbet Layer and create peaks. Freeze for at least an hour before serving. Just before serving Blow Torch the meringue.
Cut the dessert with a thin bladed knife dipped in hot water.
