One of the things I love to do is collect chestnuts from the countryside. We forage around under the sweet chestnut tree, and on finding the glossy brown nuts, break open the shells to get at the sweet nuts. I’ve noticed them piled high outside our local grocers too – for those times when I can’t forage for them.
Although I love the nuts fresh, I wanted to use them cooked and use them to flavour a dessert. So, after roasting and peeling I whizzed them in the food processor to create a seasonal alternative to ground almonds in a frangipane. Combined with some poached winter fruits they made a sophisticated tart inspired by an Angela Hartnett recipe.
What you will need
225g plain flour, plus extra for dusting
110g caster sugar
3 medium egg yolks, lightly beaten
125g butter, softened
125g caster sugar
125g ground chestnuts (roasted and peeled)
1 tbsp plain flour
Poached Pears and Quince
250g caster sugar, plus 2 tsp extra
2 good-sized pears and 2 quince
1 cinnamon stick, broken in half
2-3 strips thickly pared orange zest
1/2 vanilla pod
First make the pastry by adding the butter, flour and sugar into the food processor until the mixture resembles breadcrumbs. Add the egg yolks into the mix slowly, until the dough comes together in a ball – you might need to add 1 teaspoon cold water if the dough is very crumbly. Wrap the dough in cling film and pop into the fridge for 30 minutes or so. To make the frangipane filling cream the butter and sugar together in a large bowl until light and fluffy (or whizz in the food processor). Gradually beat in the eggs, one at a time, then fold in the ground chestnut and flour. Mix well and chill until needed. To poach the pears and quince put the sugar in a saucepan, pour in 500ml water and place over a medium heat. Stir until the sugar has dissolved. Peel the fruit and add to the pan, along with the cinnamon. Squeeze the juice from the lemon into the pan and add the squeezed lemon and orange zest. Split the vanilla pod in half, scrape out the seeds and add to the pan with the pod. Add some more water to just cover the pears. Simmer for 25 minutes, then remove the fruit to a plate with a slotted spoon. Set aside for 15 minutes, or until cool enough to handle.
Preheat the oven to 190°C/fan170°C/gas 5. On a lightly floured work surface, roll out the pastry to a circle large enough to line the tart tin. Don’t worry if it breaks up, as this is a very short, crumbly pastry – you can just patch it together in the tin , making sure it is even all over. Trim off any excess pastry and spread the frangipane evenly on top. Cut the fruit in half lengthways and, using a teaspoon, scoop out and discard the core from the centre. Cut each piece of fruit into slices and arrange on top of the frangipane filling. Bake for 55 minutes to 1 hour, until the pastry is golden and the filling is set (I made smaller tarts, so baked for a sh0rter period). Sprinkle with the extra 2 teaspoons caster sugar and bake in the oven for a further 15 minutes to finish off the browning. Cool in the tin slightly, then remove and transfer to a wire rack. Serve warm or at room temperature with a dribble of cream.
