LEMON BUTTER ICING MARY BERRY RECIPES

1. You will need a 20cm (8in) round, deep, loose-bottomed sandwich tin. Preheat the oven to 200°C/180°C fan/Gas 6.

2. First make the pastry. Measure the flour, butter and icing sugar into a food processor and whizz until the mixture resembles breadcrumbs. Add the egg and whizz until the mixture comes together. Alternatively, rub the flour, butter and sugar together in a mixing bowl with your fingertips before adding the egg.

3. Remove the dough from the bowl and gather together on a floured work surface, then lightly knead until smooth (be careful not to over-knead). Roll the pastry out thinly and transfer it to the tin, lining the base and sides. Trim the edges and prick the base with a fork, then chill in the fridge for about 30 minutes.

4. Line the pastry case with baking paper and baking beans and bake blind in the oven for about 15 minutes. Remove the paper and beans and return to the oven for a further 5–7 minutes until completely cooked, crisp and pale golden. Set aside to cool.

5. To make the filling, pour the cream into a shallow saucepan. Add the sugar and lemon zest. Stir over the heat until just boiling and the sugar is dissolved, then remove the pan from the heat and leave to stand for 5 minutes. Stir in the lemon juice and stir until the consistency has thickened slightly. Leave to cool for 5 minutes, then spoon the filling into the tart case and level the top. Place in the fridge to chill for at least 4 hours or overnight.

6. Decorate with raspberries and dust with icing sugar. Serve sliced into wedges with some pouring cream if you like.

Prepare ahead: Tart can be made up to a day ahead. Decorate on the day.

To make the pastry, measure the flour, butter and sugar into a food processor. Whiz until the mixture resembles fine breadcrumbs. Add the egg and whiz again until the dough comes together to form a ball. Turn out on to a lightly floured work surface and roll thinly. Carefully line the tin and press the pastry into the sides. Prick the base with a fork and place in the fridge to chill for 30 minutes.

Preheat the oven to 200°C/180°C fan/Gas 6 and place a baking tray in the oven to get very hot.

Line the pastry case with non-stick baking paper, add baking beans, place on the hot baking tray and bake for 15 minutes. Remove the beans and paper and bake for another 5 minutes, or until the pastry is crisp and lightly golden. Leave to cool. Reduce the oven temperature to 150°C/130°C fan/Gas 2.

To make the filling, measure the cornflour and 200ml (⅓ pint) water into a pan and whisk to combine. Add the zest and juice of the lemon and lime and place over a medium heat. Continue to whisk until the mixture has boiled and thickened. Remove from the heat, add the sugar and egg yolks and whisk again. Pour into the pastry case and place in the fridge to chill.

Meanwhile, make the meringue topping. Place the egg whites in a large bowl and whisk using an electric whisk, until stiff. Add the sugar a little at a time, whisking on full speed, until you have a shiny, glossy meringue. Spoon into a piping bag fitted with a plain 1½cm (⅝in) nozzle and pipe even blobs over the surface of the chilled custard in a neat pattern. If you don’t have a piping bag, you can use two dessertspoons.

Bake in the oven for 35–40 minutes, until pale golden on top and firm to touch. Leave to cool in the tin for 15 minutes before removing from the tin. Serve warm with pouring cream.

Mary’s tips:

Can be made up to 8 hours ahead and reheated gently to serve.

Not for freezing.

Do not serve the pie hot, as the filling may be a bit soft and will spill out of the pastry case.
