Floating Island (Île Flottante)
Île flottante Say it: eel floh-TAHNT
Île flottante is a classic French bistro dessert of airy poached meringue “islands” drifting on a pool of silky vanilla crème anglaise, finished with threads of amber caramel. It is served chilled, often at Sunday lunches and celebratory family meals across France. The contrast is the point: the meringue is cloud-light and barely sweet, the custard is rich and fragrant, and the caramel adds a faint bitter edge. It looks elegant but relies on simple pantry ingredients and careful, gentle cooking.

Method
Warm the milk with the vanilla bean and seeds in a wide saucepan over medium-low heat until steaming and small bubbles form at the edge, about 5 minutes; do not let it boil. Remove from the heat, cover, and leave to infuse for 10 minutes. Lift out the vanilla bean; if using vanilla extract, do not add it now.
In a clean bowl, beat the egg whites with the salt to soft peaks. Add the 1/2 cup (100 g) meringue sugar a spoonful at a time, beating until the meringue is glossy and forms stiff peaks that hold their shape, 3–5 minutes.
Bring the vanilla milk back to a bare simmer over low heat. Using two large spoons, shape the meringue into 8 oval quenelles and lower them gently into the milk, in batches. Poach for 2–3 minutes per side, until puffed, firm and set; lift out with a slotted spoon and drain on a plate.
Make the crème anglaise. whisk the egg yolks with the 1/2 cup (100 g) custard sugar until pale and slightly thickened. Slowly whisk in the warm poaching milk in a thin stream, then return to the saucepan. Cook over low heat, stirring constantly with a spatula, until the custard coats the back of the spoon and registers 170–175°F (77–79°C); do not boil. Strain through a fine sieve into a bowl and stir in the vanilla extract, if using. Cool slightly, then chill until cold, at least 2 hours.
For the caramel, combine the 1/2 cup (100 g) caramel sugar and water in a small heavy saucepan. Cook over medium heat without stirring, swirling the pan occasionally, until the syrup turns a deep amber, 5–7 minutes. Remove from the heat and let the bubbles settle for a few seconds.
Pour the chilled custard into shallow bowls. Float the poached meringues on top, then drizzle with warm caramel in thin threads. Serve immediately.
Regional variant: Snow Eggs (Œufs à la neige)
Instead of shaping large oval islands, drop the meringue by small spoonfuls into the simmering milk to make egg-sized dumplings. Poach them for 1–2 minutes per side, then serve several per bowl over the same crème anglaise, with caramel drizzled over the top.
Cook's notes
- Poach the meringues in milk that is barely simmering; a hard boil will make them tear and shrink.
- Whisk the custard constantly over low heat and strain it afterward for a silky texture.
- The custard and poached meringues can be made up to 1 day ahead; keep them covered and separate, and add caramel just before serving.
Serve with
Serve chilled, with coffee or a small glass of Sauternes.
Make ahead and storage
The custard and poached meringues can be refrigerated separately for up to 1 day; drizzle the caramel just before serving.
