Floating islands
Floating islands are a classic French dessert of poached meringue islands floating on vanilla custard. The Thermomix whisks the egg whites into stiff peaks with the butterfly whisk, heats the milk custard precisely without curdling, and grinds pistachios for a crunchy finish.
About this recipe
Floating islands Thermomix TM7 bring the legendary French dessert îles flottantes to your all-in-one kitchen machine. This recipes collection classic pairs a silky vanilla milk custard with airy poached meringue islands, finished with liquid caramel and ground pistachios. The TM7 handles the trickiest steps: the butterfly whisk turns egg whites and a pinch of salt into glossy, stable peaks, while gentle heating keeps the egg yolk and milk custard smooth without curdling. Homemade vanilla sugar, ground in seconds, gives deeper aroma than store-bought packets. Floating islands are the perfect make-ahead dessert for dinner parties, birthdays or a romantic weekend treat, because the meringues rest in the cold custard until serving. If you have ever struggled with curdled crème anglaise or collapsing meringue by hand, this Thermomix TM7 version solves both problems and delivers a light, gluten-free dessert that looks impressive on every plate.
Preparation tips
- Let the poached meringue islands rest in the vanilla custard in the fridge for at least a few hours before serving, so the egg whites absorb the milk flavour and become delicately creamy rather than dry.
- Drizzle the liquid caramel over the floating islands only just before serving, otherwise it dissolves into the custard and loses its glossy, bittersweet contrast against the soft meringue.
- For a nuttier result, scatter the ground pistachios over the meringue islands at the table; children usually prefer their portion without nuts and with an extra spoonful of caramel instead.
Recipe variations
- Lactose-free version: replace the milk with lactose-free whole milk or unsweetened oat drink for the custard; the egg whites, sugar and vanilla sugar stay the same, and the meringue islands poach and taste virtually identical.
- Festive version: add a splash of orange blossom water to the custard and top the islands with caramel and crushed pistachios plus a few freeze-dried raspberries for a colourful Christmas or Valentine dessert.
