For the syrup
- 125 g (4oz) sultanas
- Zest and juice of 2 oranges
- 175 g (6oz) butter, softened
- 200 g (7oz) golden caster sugar
- 4 large eggs, separated
- 125 g (4oz) each fine polenta and ground almonds
For the topping
- Juice of 1 orange
- 1 Tbsp. golden caster sugar
- 4 Tbsp. Grand Marnier
To decorate
- 200 g (7oz) mascarpone
- 1 Tbsp. icing sugar
- Zest of 1 orange
- Step 1
Line a 20.5cm (8in) cake tin with greaseproof paper. Preheat the oven to 190°C (170°C fan) mark 5. Put the sultanas into a pan with the juice of one orange. Bring to the boil and simmer gently until the sultanas are plump and the liquid has been absorbed.
- Step 2
Cream the butter, sugar and egg yolks in a bowl until soft and creamy. Add the polenta, ground almonds, soaked sultanas, orange zest and remaining juice. Fold together gently. Whisk the egg whites in a clean, grease-free bowl until soft peaks form. Add a spoonful of the egg whites to the cake mixture to loosen. Fold in remaining whites.
- Step 3
Spoon the mixture into the tin and level the top. Bake for 45min until a skewer inserted into the centre comes out clean. For the syrup, heat orange juice, sugar and Grand Marnier in a pan until the sugar dissolves. Bring to boil; simmer for 3-4min to make a syrup. Cool. Prick the cake all over and pour syrup evenly over the top.
- Step 4
For the cake topping, beat all the ingredients together in a bowl. Smooth over the cake. Decorate with the orange slices and bay leaves.
