Chilli and chocolate have become a well-loved combination. Thoroughly pureed chestnuts add a subtle sweet flavour and a grainy texture, similar to ground almonds.
(Serves 10)
4 medium eggs
140g caster sugar
250g dark chocolate
250g unsalted butter
1-2 teaspoons chilli powder, to taste
250g cooked chestnuts
275ml milk
2-3 drops almond essence
Preheat the oven to 170C/325F/gas mark 3. Grease and line a 23cm springform cake tin with baking parchment.
Separate the eggs. Beat the yolks with the caster sugar.
Roughly chop the chocolate and put it into a small saucepan with the butter. Gently melt the chocolate and butter together. Stir in the chilli powder and mix well to avoid any lumps. Leave to cool a little, then stir into the egg yolks and mix thoroughly.
Peel the chestnuts if they still have their outer skins on. Roughly chop and put them into a small saucepan with the milk. Bring to the boil, stir in the almond essence and leave to cool for a few minutes before transferring to a food processor. Process until smooth and add to the chocolate mixture, mixing well to prevent any pale streaks in the cake.
Beat the egg whites to soft peaks and gently fold them into the chocolate mixture. Spoon the mix into the prepared tin, smooth the top and bake for up to 45 minutes – it may still be a bit wobbly. Leave to cool before taking the cake out of the tin and slicing to serve.
