Makes 1 Swiss roll
Preparation time: about 45 minutes
Baking time: 14 minutes
Oven temperature: 180°C
- 4 eggs, separated
- 30ml white sugar
- 50g (60ml) castor sugar
- 5ml vanilla essence
- a pinch of salt
- 70g (125ml) flour, sifted
- 15ml cocoa, sifted
- 200ml cream
- 270g dark chocolate, coarsely grated
- about 300g berries (we used raspberries and strawberries)
1. Preheat the oven. Whisk the egg whites until they form soft peaks; add the white sugar and whisk until the mixture forms stiff peaks. Now whisk the egg yolks, castor sugar, vanilla essence and salt in a separate bowl until light.
2. Fold the flour and egg whites into the egg yolks until just combined. Don’t mix too much – try to retain as much of the air as possible. Spoon out 300ml of the batter and mix with the cocoa. Spoon this chocolate batter into a piping bag.
3. Line a 28 x 36cm baking tray with a sheet of plain white paper and, using a pencil, draw a star on the paper (use a cookie cutter as a template). Cover with a sheet of transparent baking paper and spray with non-stick spray. Cut the piping bag open and ‘colour-in’ the stars with the chocolate batter, following the pattern on the bottom sheet.
4. Bake the stars for 2 minutes. Allow to cool for 5 minutes and then spread the vanilla batter over the baked stars. Smooth it out evenly and bake for a further 12 minutes.
5. Turn the cooked Swiss roll out onto a clean chopping board while it is still warm and carefully remove the baking paper. Turn the cake over again and place it, star side down, on a new sheet of baking paper (or a clean tea towel) sprinkled with castor sugar. Using the paper to help you, roll it up carefully. Leave it to cool rolled up – this prevents the cake from cracking when you add the filling. Heat the cream for the filling to just below boiling point, pour over the grated chocolate in a mixing bowl and stir until melted. The filling should be thick, glossy and spreadable.
6. Carefully roll open the cake, spread a thick layer of chocolate on the inside and sprinkle a layer of berries over that (cut the strawberries and bigger berries smaller if necessary). Roll the cake up and serve on a pretty platter.
