Orange & almond cake with citrus mascarpone
- Preparation and cooking time
- Prep: -
- More effort
- Serves 8
- 3 large oranges
- scrap of unsalted butter
- 140g polenta , plus 1-2 tbsp
- 200g flaked almonds
- 1 scant tbsp baking powder
- 7 large eggs
- 2 large egg yolks
- 350g golden caster sugar
For the mascarpone
- 500g tub mascarpone
- 3-4 tbsp Cointreau or other orange liqeur, to taste
- 3-4 heaped tbsp homemade (or artisan) lime marmalade , to taste
- STEP 1
Boil two of the oranges (whole) in water, with the lid on the pan, for about 1 hour or until squidgy. Drain and leave to cool.
- STEP 2
Butter a springform cake tin, 23cm/9in wide and 7cm/23⁄4in deep. Add 1-2 tablespoons of polenta, tip the grains around until the tin is coated, then knock out the excess. Set aside.
- STEP 3
Whizz the flaked almonds to a grainy powder in a food processor, then mix in a bowl with the polenta and baking powder. Set aside.
- STEP 4
Halve the cooked oranges and remove any pips. Remove zest from the third orange. Whizz the zest and the orange halves (with skin on) to a smooth purée in the food processor. Set aside.
- STEP 5
Preheat the oven to 180C/Gas 4/fan oven 160C. Using a mixer or electric beaters, beat the eggs, yolks and sugar for a good 5-7 minutes until the batter looks like a very thick milkshake.
- STEP 6
Quickly beat in the almond mixture, then the purée until just blended. Pour the batter into the tin, leaving at least 1.5cm/5⁄8in at the top.
- STEP 7
Bake the cake in the middle of the oven. After 10 minutes, reduce the temperature to 150C/ Gas 2/fan oven 130C, bake for 30 minutes, then reduce temperature to 140C/fan oven 120C for a further 30 minutes (if you have a gas oven, cook at gas 4 for 10 minutes, then at gas 2 for 11⁄4 hours until done without reducing the temperature further). The cake is ready when it has risen, is golden-brown and the centre is just firm – don’t panic that it still feels fragile.
- STEP 8
Leave the cake to cool in its tin (it will sink a little), then run a palette knife around the edge before releasing the sides. Only attempt to transfer it from the metal base to a decorative plate or stand if you have a proper cake lifter.
- STEP 9
Whisk the liqueur and marmalade into the mascarpone. Serve the cake in thick wedges with the mascarpone dolloped on top.
