Yes this is really a roulade but I can’t bring myself to type that word (in my head it’s associated with hostess trolleys, raspberry pink table runners and, worst of all, glace cherries), so let’s settle on meringue roll. Regardless of the terminology though, this is delicious; hazelnut studded meringue, smooth milk chocolate cream, dark chocolate ganache and to top it off, caramel covered hazelnuts- it’s pretty much a guaranteed winner (plus it’s not as complicated to make as it looks, providing you’ve got a good whisk… or guns of steel).
For the meringue:
- 100g hazelnuts
- 4 egg whites
- 225g caster sugar
- 50g icing sugar
For the chocolate filling:
- 400ml double cream
- 3tbsp cocoa powder
- 3tbsp icing sugar
For the topping:
- 100g dark chocolate
- 100ml double cream
- handful hazelnuts
- 100g caster sugar
- Preheat the oven to 170c. Grease a 20cm x 30cm (roughly) shallow baking tin with a little butter then line with greaseproof paper. Set aside.
- Place the hazelnuts on a baking tray and roast in the oven for 5-10 minutes or until golden brown. Once golden cool a little then blitz in a food processor to create a corse crumb texture. Set aside to cool for later.
- Whisk the egg whites to form medium peaks then add the caster sugar in three additions, whisking well between each. Once you’ve added all the sugar continue to whisk until the meringue reaches stiff peaks, then add the crushed and cooled hazelnuts. Fold the nuts in carefully then tip the meringue into your prepared tin. Spread out evenly to the edges with a spatula or palette knife. Bake for 20-25 minutes or until it has some light colour.
- When your meringue is ready, place on a wire rack and leave to cool in the tin. Dust the icing sugar in an even layer over a large rectangle of greaseproof paper, ready for when you turn out the meringue.
- While the meringue is cooling, make the chocolate cream filling. To do this sift the cocoa and icing sugar into the double cream and whisk to soft peaks with electric beaters.
- When the meringue has cooled turn out onto the prepared paper. Spread the chocolate cream all over the surface, leaving a gap of about 1cm around the edge.
- Using the paper to help you, roll up the roulade lengthways. I always find it’s easier if you do this away from you, using the paper to help tease up the meringue. It will crack, but don’t worry, it’s meant to!
- When your roll is complete, make the ganache. To do this just chop up the dark chocolate and place in a bowl, then heat the cream to just below boiling and pour directly over it. Leave it to melt together then give it a stir to completely combine. Set aside to thicken a little then pipe down the centre of your roll.
- For a final (completely optional) flourish, pour the sugar into a heavy bottomed pan and heat gently. Allow the sugar to melt (do not stir, just swirl), then take it to a golden amber colour. Once it reaches this colour remove it from the heat and keep an eye on it’s consistency. Once it thickens and begins to form sugary threads, dip the whole hazelnuts in and pull out to create spiky caramel coated nuts- the perfect decoration!
