Initially, this popular dessert was simply called "snow eggs", the main ingredient being those sweet egg whites which, once poached, cooked in a bain-marie or (mostly) whipped, accompanied a jelly or a liquid cream.
A very simple composition compared to that of Auguste Escoffier, which at the beginning of the 20th century consisted of cookies from Savoy soaked in kirsch and marasch, which, once covered with apricot jam, were coated with sweetened and vanilla Chantilly and then decorated with slivered pistachios, currants and chopped almonds.
It is assumed that the man who was one of the founders of French gastronomy was inspired by an 1880's dessert: a cooked and sweetened apple puree incorporated into egg whites previously beaten and perfumed with orange blossom, which were then placed on an upside down cream.
Today's recipe is based on these two elements, prepared separately but served together: a custard decorated with egg whites beaten to a stiff consistency, which are first immersed for a few minutes in simmering milk (sweetened and flavored with vanilla like the cream).
The cooking of the "snow eggs" is very delicate because of the lightness of the white mousse, as well as the addition of other garnishes such as roasted almonds or crushed pralines and, depending on the region, caramel or lemon zest.
On the menu of every French restaurant, the floating island surely owes its timeless success to its aesthetic appearance and its poetic name. Or is it its apparent lightness that, compared to the more traditional pastries made with pastry and fruit, offers food lovers an attractive alternative?
