Chocolate and Beetroot cake

This is a great recipe I found from the Telegraph on line. Its surprisingly easy to make. I have not changed anything from the original as it was perfect as it was! Recipe by Diana Henry and photo by Yuki Sugiura.

Ingredients:
250g (9oz) cooked beetroot (fresh not pickled!)
75g (2¾oz) dark chocolate, broken into pieces
125g (4½oz) butter, softened
300g (10½oz) soft light-brown sugar
3 eggs
50g (1¾oz) cocoa powder, sifted
225g (8oz) self-raising flour, sifted
¼ tsp salt

For the icing
150g (5½oz) good-quality plain chocolate, broken into small pieces
140ml (5fl oz) sour cream
5 tbsp icing sugar, sifted
3 tbsp crème de cassis
grated white chocolate, for decorating (optional)

Method
Grate the beetroot quite coarsely. Put the chocolate into a bowl set over a pan of simmering water and melt. Put the butter, sugar and eggs in a mixer and beat until light and pale. Add the melted chocolate then fold in the cocoa powder, flour and salt. Finally, stir in the beetroot.

Pour the batter into a greased cake tin measuring 20-23cm (8-9in) and cook in an oven preheated to 180°C/350°F/gas mark 4 for 45 to 50 minutes. The cake is ready when a skewer inserted into the middle comes out clean. Turn on to a wire rack to cool.

Put all the icing ingredients except the cassis in a bowl and set over simmering water. Allow to melt, but don?t let it get too hot. Take off the heat and add the cassis. Stir vigorously until you have a smooth, glossy mixture. Leave to cool and thicken. Spread over the cake with a palette knife, then scatter with grated white chocolate. Leave the icing to set before serving with crème fraîche.
