What is "floating island"?

Floating island is a classic French dessert that is made from a mixture of egg whites, sugar, and milk or cream. The egg whites are whipped until they form stiff peaks, and are then poached in a mixture of milk and sugar until they are set. The poached egg whites are then removed from the milk mixture and placed in a dish, and the milk mixture is sweetened and flavored with vanilla or other flavorings, and is sometimes thickened with cornstarch or gelatin. The sweetened milk mixture is then poured over the poached egg whites, creating a "floating island" effect. The dessert can be garnished with a sprinkle of cinnamon or nutmeg, and is often served chilled. Floating island is known for its delicate and airy texture and its sweet and creamy flavor.
