Using a channel knife, cut a few grooves into the orange peels. Cut the tops off the oranges and reserve. Empty the entire fruit of the orange pulp, being careful not to create a hole in the bottom. Freeze the empty orange rinds to create shells.

In a bowl, combine the egg yolks with 1/2 cup of the sugar and beat until thick and a pale yellow. If using an electric mixer, mix for 5 to 7 minutes. Add the lemon curd or marmalade, orange liquer, and vanilla. Mix well.

In a separate cold bowl, whip the cream until firm. Set aside.

In another bowl at room temp, beat the egg whites until soft peaks form.

In a large stainless steel bowl, blend the whipped cream and the egg yolk mixture. GENTLY fold in the egg whites. Transfer the mixture to a pastry bag fitted with a large tip. Remove orange shells from freezeer and pipe the mixture into them, extending 1 inch higher than the top of the orange. Freeze for at least 4 to 5 hours. Add the tops and serve right out of the freezer with Lime and Yogurt Sauce.

*RAW EGG WARNING

Food Network Kitchens suggest caution in consuming raw and lightly-cooked eggs due to the slight risk of Salmonella or other food-borne illness. To reduce this risk, we recommend you use only fresh, properly-refrigerated, clean, grade A or AA eggs with intact shells, and avoid contact between the yolks or whites and the shell.

Mix all the ingredients in a food processor until very smooth.
