Step-by-Step Directions
1. Make the Crème Anglaise
- In a small pot over medium heat, combine the cream, milk, vanilla bean, pinch of salt, and 1/4 cup sugar. Bring just to a simmer.
- In a medium bowl, whisk together the egg yolks and remaining 1 cup sugar until smooth.
- Temper the egg mixture: Slowly pour about one-third of the hot milk mixture into the egg yolks, whisking constantly.
- Return all to the pot. Cook over medium-low heat, stirring constantly, until thick enough to coat the back of a spoon. Do not let it boil.
- Strain into a medium bowl for ultra-smooth texture. Chill in the refrigerator until cold.
2. Prepare the Meringue Islands
- In the bowl of a stand mixer, whip egg whites and cream of tartar to soft peaks.
- Gradually add sugar. Continue beating until stiff, glossy peaks form.
- Simmer 1 cup whole milk in a small pot. Drop the meringue by 2–3 tablespoon-sized scoops into the hot milk.
- Poach gently for 2–3 minutes. The meringue will puff and set; remove until firm and drain on a towel or rack.
3. Final Assembly & Garnishing
- Warm the raspberry jam until pourable. Divide crème anglaise between serving bowls.
- Swirl jam over the custard for flavor and decorative appeal.
- Set poached meringues atop the custard pools.
- Garnish with fresh raspberries and toasted pistachios for crunch and color.
- Serve immediately while textures are at their peak.
Tips for Perfect Floating Islands
- Egg whites: Use room-temperature eggs for the meringue—whip gradually for stable, lofty peaks.
- Poaching: Keep the milk at a bare simmer; boiling may break the meringue or form tough skins.
- Custard: Low, gentle heat prevents curdling. Stir with a heatproof spatula and check with the back-of-spoon test.
- Assembly: Chill both the meringue and custard for optimal texture and flavor contrast.
Creative Twists & Variations
- Caramel threads: Melt sugar to amber, drizzle into decorative cages for dramatic presentation.
- Flavor infusions: Add citrus zest, swap vanilla for almond, or incorporate floral extracts.
- Nutty accents: Substitute almonds or hazelnuts for pistachios; toast and chop before garnishing.
- Seasonal jams: Apricot, blackberry, or strawberry jams make striking alternatives to raspberry.
Nutrition & Allergy Notes
- Gluten-free: The classic recipe contains no wheat or gluten.
- Dairy-free options: Substitute plant-based cream and milk for crème anglaise if needed; adjust flavorings accordingly.
- Eggs: Essential for both custard and meringue; not recommended for those with egg allergies.
Serving Suggestions
- Individual bowls: Present each diner with a personal island in a shallow bowl for visual impact.
- Family style: Arrange meringues atop a large dish of custard; swirl jam and sprinkle garnishes for sharing.
- Pairings: Serve with dessert wines or light roasted teas for balance.
Common Mistakes and How to Avoid Them
- Curdling custard: Stir constantly over gentle heat. If small lumps appear, strain immediately.
- Collapsed meringue: Ensure stiff peaks before poaching; avoid overmixing after adding sugar.
- Poor presentation: Use contrasting garnishes—colorful berries, golden nuts, and shiny caramel for appeal.
Frequently Asked Questions
What is the key to a silky crème anglaise?
Constant stirring over low heat and straining through a fine mesh sieve ensures a custard that’s creamy and lump-free.

Crème anglaise may be made a day ahead and chilled. The meringues are best poached, cooled, and served within a few hours to maintain their airy texture.

Yes. Toasted almonds, hazelnuts, and a variety of fruit jams (apricot, blackberry, strawberry) are delicious alternatives.
What does ‘floating’ refer to in this dessert?
The poached meringue pieces are set atop the pool of custard, appearing to float on its surface—a striking presentation hallmark.
