LEMON CUSTARD TARTS RECIPES

Steps:

• Using a pastry brush, grease eight individual pastry tins generously with the melted butter, then chill in the fridge. Put the butter between two sheets of baking parchment, then bash and roll into a large rectangle roughly the thickness of a £1 coin. In a large bowl, mix the flour with 150ml water and a pinch of salt using a wooden spoon. Tip the dough onto a clean surface and knead for 5 mins until smooth.
• Shape the dough into a rough rectangle, cover with cling film and rest in the fridge for 20 mins. If your butter is getting too soft, put it in the fridge to chill too. Roll the dough out into a large, thin rectangle at least twice the size of the butter. Put the butter in the middle of the dough, fold all the edges up over it to encase it, then fold the dough over itself in half.
• Roll out the dough to roughly half its original size, then fold in half, then half again to make a rectangle a quarter the size of the original. Repeat this process once more, flouring your work surface if you need to. Don’t worry about being too precise here, or if the butter starts breaking through some of the layers. Cover and put the pastry in the fridge to rest for 20 mins.
• On a floured surface roll the chilled dough into a thin A3-sized rectangle, then roll it up lengthways into a tight sausage shape. Divide the pastry into three, the middle section will make your perfect looking tarts, then wrap and freeze the rest for another time. (It would also make delicious palmier biscuits if you roll it out and sprinkle with sugar.)
• Slice the pastry into 8 discs. Work the discs into the tins with your fingers, pressing and stretching them to fill the tins. If the layers start to come apart, press them back together. Chill while you make the custard.
• In a pan, warm 150ml milk with the cinnamon stick, lemon peel and half the butter until just simmering and the butter has melted. In a large bowl, sieve the cornflour and flour into the remaining milk and whisk to form a thin paste. Pour the warm milk mixture over the flour paste and leave to infuse for a few mins. Sieve the custard back into the pan, heat gently and keep stirring for 3-4 mins until it reaches the consistency of double cream. Take off the heat and blend in the remaining butter.
• Put the syrup ingredients in a frying pan and stir over a medium heat for 5 mins until you have a light, fragrant caramel. Take the pan off the heat and carefully pour in 100ml water. Return the pan to a low heat until the sugar has melted again into a syrup. Strain into a bowl.
• Slowly add half the syrup to the custard and whisk until completely blended. You can store the custard in the fridge from this point, but don’t add the eggs until just before you are ready to cook the tarts. Heat your oven to 260C/240C fan/gas 8 or as high as your oven will go. Put a baking tray on the top shelf of the oven to heat up. Whisk the egg yolks in a small bowl, then incorporate into the custard. Pour the mixture into the pastry bases.
• Put the filled tin on the hot baking tray. Put the tray in the middle of the oven and bake for 5- 8 mins, or until the custard starts to puff up. Once the custard has puffed up, turn the oven onto its grill setting and transfer the tarts to the top shelf. Grill for 1-2 mins or until caramelised – the darker the better. Remove from the oven and brush with a little of the remaining syrup. Let the tarts cool slightly in the moulds before turning out onto a cooling rack.

Steps:

• Mix the butter and sugar together in the bowl of an electric mixer fitted with a paddle attachment until they are just combined. Add the vanilla. In a medium bowl, sift together the flour and salt, then add them to the butter-and-sugar mixture. Mix on low speed until the dough starts to come together. Dump onto a surface dusted with flour and shape into a flat disk. Press the dough into a 10-inch-round or 9-inch-square false-bottom tart pan, making sure that the finished edge is flat. Chill until firm.
• Meanwhile, preheat the oven to 350 degrees F.
• Butter 1 side of a square of aluminum foil to fit inside the chilled tart and place it, buttered side down, on the pastry. Fill with beans or rice. Bake for 20 minutes. Remove the foil and beans, prick the tart all over with the tines of a fork, and bake again for 20 to 25 minutes more, or until lightly browned. Allow to cool to room temperature.
• Remove the zest of the lemons with a vegetable peeler or zester, being careful to avoid the white pith. Squeeze the lemons to make 1/2 cup of juice and set the juice aside. Put the zest in a food processor fitted with a steel blade. Add the sugar and process for 2 to 3 minutes, until the zest is very finely minced. In the bowl of an electric mixer fitted with a paddle attachment, cream the butter with the sugar and lemon zest. Add the eggs, 1 at a time, and then add the lemon juice and salt. Mix until combined.
• Pour the mixture into a 2-quart saucepan and cook over low heat, stirring constantly, until thickened, about 10 minutes. The lemon curd will thicken at about 175 degrees F, or just below a simmer. Remove from the heat.
• Fill the tart shell with warm lemon curd and allow to set at room temperature.
