Pears baked in Moscatel with hazelnut cake

Preheat the oven to 180ºC, gas mark 4. Butter a 23cm diameter round, 5cm deep cake tin, then line the base with baking parchment. Toast the hazelnuts in a dry frying pan for 3-4 minutes until golden in places. Cool completely.

Whizz the hazelnuts in a food processor until fine but with some coarser bits. Use the pulse button, as nuts can become sticky and oily if processed too fast.

Put the egg whites into a large clean bowl and the yolks in another. Add 175g caster sugar to the yolks and beat with an electric hand mixer until pale and doubled in volume. Beat in the vanilla. Wash the beaters well.

Beat the egg whites until stiff peaks form. Add 1 tbsp caster sugar to the whites and beat again. Fold ⅓ of the whites into the egg yolk mixture, followed by ½ the ground hazelnuts. Fold in the next ⅓ of the whites and the remaining hazelnuts. Add the remaining whites and quickly fold in the butter and lemon zest.

Scrape the batter into the cake tin. Bake for 30 minutes. Check for doneness by putting a skewer into the centre of the cake. It should come out clean, with no batter clinging to it.

Leave to cool for 20 minutes, then run a fine knife between the cake and the tin. Turn the cake out onto a wire rack to cool completely. It will keep for a couple of days in a sealed box or tin, so you can make this well in advance.

For the pears, turn the oven up a little to 190ºC, gas mark 5. Halve the pears lengthways, leaving the skin on and the core in or out as you wish. Arrange them, skin-side down, in a roasting tin or a gratin dish in which they can lie snugly in a single layer.

Pour the Moscatel, lemon juice and 100ml water into the pan and arrange the lemon zest around and under the pears. Add the cinnamon stick. Sprinkle 100g soft sugar over and around the pears and bake for 40-45 minutes, until golden and starting to shrivel a little at the edges. During the cooking process, spoon some of the juices over the pears.

Spoon the juices over the pears 10 minutes before they are done, then sprinkle with the remaining soft sugar and return to the oven.

Arrange the pears in a serving dish with the sauce and serve warm or at room temperature, with crème fraîche and the hazelnut cake. Dust the cake with icing sugar just before serving.
