Chetna Makan (chef and GBBO semi-finalist) creates a sumptuous organic cardamom and chocolate tart, using organic chocolate.
To make the pastry, mix the flour and sugar in a large bowl. Add the butter and coat it with the flour.
Use your fingertips to rub the butter into the flour until the mixture looks like breadcrumbs. Mix the egg and lemon juice together and pour in just enough of the liquid to bring the dough together. You might not need all the liquid. Gently knead the dough on a lightly floured surface for a few seconds then shape it into a ball. Wrap in cling film and leave to rest in the fridge for 10-15 minutes.
Preheat the oven to 180°C. On a floured surface, roll the pastry to the thickness of a pound coin. Line a 23cm loose-bottom tart tin with the pastry, leaving the excess hanging over the edge, and prick the base all over with a fork.
Line the tart case with baking parchment, fill with baking beans and bake for 20 minutes. Remove the paper and beans and continue baking for a further 20 minutes or until the pastry looks dry and crisp. Use a small sharp knife to trim the excess pastry from the rim and leave the tart case to cool in the tin for 15 minutes.
To make the chocolate ganache, heat the cream in a pan and add the crushed cardamom seeds. When
it is about to start boiling, pour this cream over roughly chopped chocolate. Stir the mix and let the heat melt the chocolate. When done, add the butter and let it melt. Pour the ganache into the cool tart case. Put it back in the fridge to set. This might take up to 2 hours.
In a bowl, whisk the cream, mascarpone and sugar into soft peaks. Spread this over the set chocolate ganache and leave it in the fridge until ready to serve.
To serve, sprinkle some cocoa powder and hazelnuts, then place a piece of brittle on each portion and a tiny little piece of the gold leaf.
