Polenta cake

Preheat the oven to 170°C, gas mark 3. Grease an 18cm square loose-bottomed tin and line the base and sides with baking parchment.

Cream together the butter and sugar using an electric hand mixer until pale and fluffy. Add the eggs 1 at a time, beating well between each addition. Stir in the dry ingredients and beat until smooth, then fold in the orange zest and mixed peel.

Scrape the batter into the prepared tin and level the surface. Place on a baking tray. Bake for 50-55 minutes, until risen and fairly firm (it will have a very slight wobble in the middle). Test the cake using a skewer – it should come out clean when inserted into the centre.

While the cake is baking, make the orange syrup. Place the sugar and orange juice into a small saucepan and bring to the boil. Allow to simmer for 1 minute, then remove from the heat. When the cake is done, remove from the oven and, while still hot, brush the warm syrup all over, then leave to cool completely on a wire rack. The cake may sink slightly in the centre, but this is normal for polenta cakes.

To finish, make the sugared peel by tumbling together the mixed peel and granulated sugar until well coated. Sprinkle over the top of the cake, then serve.
