A festive classic tp try at home!
- vegetable oil, for greasing
- 150g/5½oz golden caster sugar
- 6 large free-range eggs, separated
- 250g/9oz high quality dark chocolate (minimum 60 per cent cocoa solids)
For the butter cream icing filling
- 250g/9oz unsalted butter, softened
- 450g/1lb golden icing sugar, plus extra for dusting
- 50g/1¾oz cocoa powder, sifted
- 2 tbsp milk
For the cream filling
- 400ml/14fl oz double cream, lightly whipped
- 250g/9 oz raspberries
- dash whisky liqueur (optional)
- This Christmas roll can be made two ways: with butter cream icing and festive decorations, or filled with cream and berries.
- Preheat the oven to 220C/425F/Gas 7. Line a 23x33cm/9×13 in Swiss roll tin with greaseproof paper and brush this lightly with oil.
- Combine the caster sugar and egg yolks in a bowl and whisk them together until light and thick. Melt the chocolate with 4tbsp cold water in a bowl over a pan of very gently simmering water. When you can see the chocolate has melted until smooth, stir in the sugar and egg mixture.
Technique: Melting chocolate
- Meanwhile, whisk the egg whites until stiff but not dry. Gently fold a spoonful of the egg whites into the chocolate mixture to lighten it, then fold in the remaining whites using a large metal spoon. Do not over mix, and always use a gentle action. Pour the batter gently into the prepared tin and bake for 12-14 minutes (no longer), until risen and just firm to the touch.
- Remove to a wire rack and leave to cool in the tin for at least 2 hours.
- Once cold, lay a sheet of greaseproof paper on a board. With one bold movement, turn the whole cake onto the sheet of paper, then lift the tin off. Carefully peel away the paper and trim away any scraggy edges of cake.
- To make the butter cream icing, beat the butter until soft, then sift in the icing sugar and cocoa. Add the milk and combine together until soft. Spread half the icing over the cake up to the edges.
- Roll up as you would a Swiss roll: starting at the long side opposite you, use the paper to roll the cake towards you, around the icing; don’t worry about the cracks. Transfer to a flat serving dish. Carefully spread the remaining icing over the cake (you can pipe the icing if you like). Chill until needed, then decorate with festive decorations and sift over some icing sugar.
