Method
Preheat the oven to 160°C (320°F). Lightly grease a 23x33cm baking sheet and line it with parchment paper.
In a spotlessly clean mixing bowl, beat the room temperature egg whites on medium speed until soft peaks form.
Increase the mixer speed to medium-high and mix in the caster sugar one tablespoon at a time. Continue mixing until the meringue is stiff, glossy, and the sugar is completely dissolved.
Gently fold the white wine vinegar, cornstarch, and finely chopped roasted hazelnuts into the glossy meringue using a large metal spoon or spatula, keeping as much air in the mixture as possible.
Shape the meringue by spreading it evenly onto the prepared baking sheet with an offset spatula, smoothing the top into an even layer.
Bake in the preheated oven for 25 to 30 minutes. The meringue is ready when it has formed a delicate crust and feels slightly springy to the touch.
Remove from the oven and allow the meringue to cool in the pan for 5 minutes, then turn it out onto a fresh sheet of parchment paper dusted lightly with extra icing sugar. Peel away the original baking parchment and cool completely on a wire rack.
Whip the cold heavy whipping cream, sifted icing sugar, and vanilla extract in a chilled bowl until stiff peaks form.
Assemble the roulade by spreading the whipped cream evenly over the cooled meringue, leaving a small 2cm border around the edges. Scatter the drained citrus segments and white chocolate evenly over the cream.
Roll the meringue tightly, starting from one of the short ends. Use the underlying parchment paper to lift and encourage the meringue to roll over itself. Transfer to a serving platter, seam side down.
Chill the finished roulade in the refrigerator for at least one hour to allow the layers to set before slicing.
Chef's Notes
- Ensure your mixing bowl and whisk are completely free of grease before whipping egg whites. Wiping them with a little lemon juice or white vinegar provides excellent insurance.
- Patience is critical when adding sugar to the egg whites. Adding it too quickly can deflate the meringue and result in a granular, weeping texture after baking.
- When segmenting the citrus fruits (supreming), do so over a separate bowl to catch the juices. Use only the drained segments for the filling to prevent a soggy meringue.
- Do not panic if the meringue cracks while you roll it. Cracking is completely normal for a roulade and actually enhances its appealing, rustic appearance.
Storage
Refrigerator: 24 hours — Store in an airtight container. The meringue will soften as it absorbs moisture from the cream, so it is best enjoyed within 24 hours.
Troubleshooting
Meringue cracks severely and breaks apart when rolling
Cause: The meringue was overbaked or left to dry out for too long before rolling
Fix: Use the whipped cream as a glue to hold it together, and dust heavily with icing sugar to mask cosmetic cracks. A rustic appearance is expected.
Prevention: Bake only until a light crust forms; the interior must remain soft. Do not let it sit uncovered for hours before assembling.
Egg whites will not whip to stiff peaks
Cause: Trace amounts of fat or egg yolk in the bowl or on the whisk
Fix: Cannot be fixed. You must start over with fresh egg whites and clean equipment.
Prevention: Wipe down the mixing bowl and whisk with lemon juice or white vinegar before starting. Separate eggs carefully.
Roulade collapses into a soggy mess after a few hours
Cause: Excess moisture from the fresh citrus segments soaked into the meringue
Fix: Cannot be fixed once assembled. Serve immediately as a messy Eton Mess-style dessert.
Prevention: Thoroughly pat the citrus segments dry with paper towels before scattering them over the cream.
Cultural Context
The meringue roulade is a delicate European dessert that shares its culinary lineage with the Pavlova and the traditional Swiss roll. It combines the classic French mastery of aerated egg whites with a modern appreciation for texturally contrasting, lighter desserts. The interplay between the crisp exterior and the marshmallow-like interior makes it a celebrated centerpiece for spring and summer gatherings.
