For the cake
- 200 g bar Bournville chocolate
- 125 g (4oz) butter, cubed
- 8 medium eggs, separated
- 200 g (7oz) golden caster sugar
For the chocolate curls and ganache
- 200 g bar Bournville chocolate
- 75 ml (3fl oz) double cream
- 25 g (1oz) butter
- Step 1
Preheat the oven to 180°C (160°C fan oven) mark 4. Grease and line a 23cm (9in) springform cake tin.
- Step 2
Melt chocolate and butter in a bowl over a pan of simmering water. Remove from heat and cool for a few minutes.
- Step 3
Put the egg yolks and sugar in the bowl of a freestanding mixer. Whisk together until pale and moussey, then whisk in the chocolate mixture.
- Step 4
Whisk the egg whites in a clean, grease-free bowl until soft peaks form. Add a third of this to the chocolate mixture and fold in using a large metal spoon. Add the remaining egg white and mix everything together, then pour into the prepared tin and bake for 1hr 15min. Turn off the oven. Cover with a damp tea-towel and leave in the oven until the cake cools and the centre has sunk.
- Step 5
Meanwhile, to make the chocolate curls, melt half the chocolate in a bowl in a 900W microwave on High for around 1min. Pour into a small rectangular container (a 250g margarine tub is perfect) and leave to cool so the chocolate hardens.
- Step 6
To make the ganache, put remaining chocolate, cream and butter in a bowl and melt in a 900W microwave on High for 1-2min. Mix together. Take cake out of tin and peel off the paper. Put on a serving plate then ladle the ganache over so it covers the top of the cake and drizzles down the sides. Leave until just set.
- Step 7
To finish the chocolate curls, upturn the tub of cooled chocolate and pop the set chocolate block out of the container on to a board. Use a very sharp knife or vegetable peeler to scrape against the chocolate to make curls.
- Step 8
Using a palette knife, scatter the chocolate curls on top of the cake.
