Lemon posset tart with raspberries

Step 1

To make the pastry, put 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. Tip it onto a floured work surface and lightly knead until smooth (be careful not to over-knead). Roll out thinly and line a 20cm/8in loose-bottomed quiche tin or deep sandwich tin. Prick the base with a fork and chill in the fridge for about 30 minutes.

Step 2

Preheat the oven to 200C/180C Fan/Gas 6.

Step 3

Line the pastry case with baking paper and baking beans. Bake for about 15 minutes, then lift out the paper and beans and return the pastry case to the oven for a further 5–7 minutes, or until it is pale golden, dry and crisp. Set aside to cool.

Step 4

To make the lemon posset, put the cream, sugar and lemon zest into a saucepan and heat until just boiling, stirring until the sugar has dissolved. Remove from the heat and leave to stand for 5 minutes. Add the lemon juice and stir until the mixture has thickened slightly. Leave to cool for 5 minutes, then spoon into the pastry case and level the top.

Step 5

Chill in the fridge for at least 4 hours, or overnight, until set.

Step 6

To serve, decorate with raspberries, dust with icing sugar and slice into wedges. Serve with pouring cream if liked.
