Chocolate Tart Recipe

Start by making the tart base. Cream the butter and icing sugar together, then add the flour, hazelnuts, salt and zest. Add 30g of the beaten egg and slowly mix together until it forms a dough. Lightly need to form a ball, wrap in cling film and rest for 1 hour in the fridge before use

Preheat the oven to 170°C/gas mark 3. Remove the pastry dough from the fridge and roll it out onto a flat work surface to a thickness of 5mm. Use a 23cm loose bottomed tart tin and line with great proof paper. Next, carefully line the tin with the rolled pastry

Brush the tart base with the egg wash and blind bake until the tart is golden brown, about 15-20 minutes. Allow to cool while you make the chocolate filling

For the filling, place the chocolate pistoles in a large mixing bowl. In a pan, heat the trimoline with the cream until hot, being careful not to boil. Once hot, pour it over the chocolate pistoles and stir until the chocolate has melted. Once the chocolate has melted, add butter and continue to stir until fully melted

Spoon a little chocolate filling around the edges of the tart base to fill in any holes. Allow this chocolate to set in the fridge, then pour in the rest of the chocolate mix to fill the ring

Place the chocolate tart to set in the fridge for at least 4 hours, or ideally overnight. To serve, use a hot knife to cut the tart into slices
