Floating Island with Bourbon Vanilla: The Recipe and Technique for Crème Anglaise
Floating island is a deceptively modest dessert: poached egg whites floating on crème anglaise. On paper, it sounds simple. In practice, it is one of the most technical desserts in French pastry, as it does not forgive any mistakes—a failed crème anglaise becomes a sweet omelet, and overcooked egg whites become rubbery.
It is also a dessert that reveals the quality of the vanilla: crème anglaise is a raw custard cooked at a low temperature, where every aromatic nuance of the pod is expressed without being masked by oven baking or by other powerful ingredients.
Ingredients (serves 6)
For the crème anglaise:
- 500 ml whole milk
- 6 egg yolks
- 100 g caster sugar
- 1 Grand Cru Bourbon vanilla pod—our Or Noir Vanilla pods
For the egg whites:
- 6 egg whites
- 50 g caster sugar
- 1 pinch of salt
For the caramel:
- 100 g caster sugar
- 2 tablespoons water
The recipe in 5 steps
Step 1: Infuse the milk Split the vanilla pod in half and scrape out the seeds. In a saucepan, bring the milk to a simmer with the pod and the seeds. Turn off the heat, cover, and leave to infuse for 20 minutes.
Step 2: Prepare the crème anglaise Whisk the egg yolks with the sugar until the mixture is slightly pale. Remove the vanilla pod from the milk, reheat the milk, then gradually pour it over the yolks while whisking. Pour the mixture back into the saucepan and cook over low heat, stirring constantly with a spatula in figure-eight motions, until the cream coats the back of the spoon (83–85°C if you have a thermometer). Never exceed 85°C: beyond that, the yolks will curdle and the cream will split. Strain and refrigerate.
Step 3: Whisk the egg whites Whisk the egg whites with the pinch of salt. When they begin to foam, add the sugar in 2–3 additions while continuing to whisk, until you have a firm, glossy meringue that forms a bird’s beak at the end of the whisk.
Step 4: Poach the egg whites Bring a large saucepan of water to a gentle simmer (not a full boil). Using two tablespoons, form quenelles of egg whites and poach them for 1–2 minutes on each side, turning them carefully. Drain on absorbent paper.
Step 5: The caramel and plating Heat the sugar and water in a saucepan over medium heat without stirring, until you have an amber caramel. Pour the cold crème anglaise into shallow bowls or dessert glasses, place the poached egg whites on top, and drizzle with caramel just before serving.
The educational point: why crème anglaise reveals everything about the quality of a vanilla pod
Crème anglaise is probably the preparation that tests a vanilla pod most thoroughly, for one simple reason: it is a custard cooked at a low temperature (never above 85°C), without flour or starch to thicken it, and without an oven to concentrate the aromas. Nothing is there to mask or artificially intensify the vanilla’s fragrance—only the infusion in warm milk does the work.
This is why the vanillin content of a pod matters so much. Vanillin is the main aromatic compound in vanilla, but a quality pod contains many more—more than 250 aromatic compounds have been identified to date, responsible for woody, floral, or slightly spicy notes depending on the origin. A Sambava Bourbon pod generally has a vanillin content of over 2.5%, compared to sometimes less than 1% for poorly cured or overly old pods. In a crème anglaise, this difference is immediately apparent: a poor pod produces a cream that tastes like “sweetened milk,” while a rich pod makes a truly flavored crème anglaise, with the full-bodied, slightly woody taste that characterizes Bourbon vanilla.
Crème anglaise does not forgive anything: choose a real Bourbon vanilla. Our Sambava pods are 16–18 cm long, contain over 2.5% vanillin, and are harvested by hand. 10% off your first order with the code BIENVENUE10. 👉 Order on ornoirvanilla.fr
Variations
Floating island with salted caramel: add a pinch of fleur de sel to the caramel at the end of cooking for a more indulgent version.
Floating island with praline: sprinkle toasted slivered almonds or praline pieces over the egg whites just before serving.
Floating island in minutes: for an express version, replace the egg whites poached in a saucepan with microwave cooking (30 seconds at full power in a buttered bowl)—less traditional, but quick and without the risk of ruining the poaching.
Frequently Asked Questions
How can I tell if my crème anglaise is cooked without a thermometer? Dip the spatula into the cream and draw a line with your finger on the back: if the line remains clear and does not close, the cream is ready. Remove it from the heat immediately, as residual heat will continue to cook it for a few seconds.
My crème anglaise has split; can it be saved? Yes, often: immediately blend it with an immersion blender while it is off the heat, or pass it through a fine sieve. The result will be less smooth than a perfectly made cream, but it can be saved.
Why do my poached egg whites fall apart in the water? The water is boiling too vigorously. It should barely simmer—small, discreet bubbles, never a full boil, otherwise the quenelles of egg whites will break into pieces.
How long does floating island keep? The crème anglaise and poached egg whites can be stored separately for 24 to 48 hours in the refrigerator. Only assemble them just before serving, and make the caramel at the last minute so it remains crisp.
