In a stand mixer or with a hand mixer, beat 1/2 cup of the milk and dry whipped topping mix in a large bowl for 4 minutes, or until light and fluffy. Set aside. In another large bowl, beat 1 jar of lemon curd, lemon pudding mix, and remaining 1/2 cup of milk for 2 minutes, or until smooth and beginning to thicken. Fold whipped topping mixture into lemon pudding mixture. Spoon into pie crust. Spread slightly thawed whipped topping over lemon mixture. Swirl remaining lemon curd through whipped topping. Freeze for 30 minutes before serving. Decorate pie with sugared lemon slices, if desired.
Sugared Lemon Slices:
Cut a clean, dry lemon into very thin slices. Using a pastry brush, evenly coat both sides of each slice with egg whites. Sprinkle with sugar and let dry on a wire rack.
Consumption of raw or undercooked eggs, shellfish and meat may increase the risk of foodborne illness.
