An overhead shot captures this elegant Plum Custard Tart resting on a vintage white ceramic cake stand. Natural window light highlights the glossy plums arranged in concentric circles, their deep purple-red color contrasting beautifully against the pale golden custard. A cross-section view reveals the crisp shortcrust base, the velvety custard layer, and the tender baked plums on top. The tart is dusted with a light shower of powdered sugar and garnished with a sprig of fresh mint for contrast. Several whole plums and scattered flaked almonds create a rustic scene around the tart, while a slice has been removed to showcase the perfect layers and the smooth, just-set consistency of the custard.

Directions

<ol class="no-list-style"> <li class="MethodStepper"> <h4 class="step-title">Step 1</h4> Start with the pastry. Place the flour and salt in a large bowl, then add the cold cubed butter. Using your fingertips, rub the butter into the flour until the mixture resembles breadcrumbs. The cold butter creates pockets of steam during baking, resulting in a flaky texture, so work quickly to prevent the butter from warming too much. </li> <li class="MethodStepper"> <h4 class="step-title">Step 2</h4> Stir in the caster sugar, then add the egg yolk and 2 tablespoons of ice-cold water. Mix with a knife until the dough starts to come together, adding the extra tablespoon of water if needed. The dough should hold together when pressed but shouldn't feel sticky. Form into a disc, wrap in cling film, and refrigerate for at least 30 minutes to relax the gluten and firm up the butter. </li> <li class="MethodStepper"> <h4 class="step-title">Step 3</h4> While the pastry chills, prepare the custard. Pour the milk into a medium saucepan, add the split vanilla pod and seeds, then gently heat until just below simmering point. Remove from heat and leave to infuse for 10 minutes, allowing the vanilla to release its aromatic compounds into the milk. </li> <li class="MethodStepper"> <h4 class="step-title">Step 4</h4> In a heatproof bowl, whisk together the egg yolks, sugar, and cornflour until pale and thick. The cornflour acts as a stabilizer, ensuring your custard sets perfectly without curdling. Remove the vanilla pod from the warm milk, then gradually pour the milk over the egg mixture while whisking constantly to prevent the eggs from scrambling. </li> <li class="MethodStepper"> <h4 class="step-title">Step 5</h4> Return the mixture to the saucepan and cook over medium-low heat, stirring constantly with a wooden spoon, until the custard thickens enough to coat the back of the spoon. This may take 5-7 minutes - patience is key here! When you run your finger through the custard on the back of the spoon, it should leave a clean line that doesn't immediately fill in. Pass through a fine sieve into a clean bowl, cover the surface directly with cling film to prevent a skin forming, and allow to cool completely. </li> <li class="MethodStepper"> <h4 class="step-title">Step 6</h4> Preheat your oven to 190°C (170°C fan). Roll out the chilled pastry on a lightly floured surface to about 3mm thickness, making it large enough to line your tart tin with a little overhang. The pastry should be thin but not so thin that it tears easily. Carefully drape the pastry over your rolling pin to transfer it to the tin. </li> <li class="MethodStepper"> <h4 class="step-title">Step 7</h4> Press the pastry gently into the corners of the tin without stretching it, as this can cause shrinkage during baking. Trim the excess pastry, leaving a small overhang to allow for shrinkage. Prick the base all over with a fork to prevent air bubbles, then line with baking parchment and fill with baking beans or rice. This blind baking technique ensures a crisp base that won't become soggy when filled with custard. </li> <li class="MethodStepper"> <h4 class="step-title">Step 8</h4> Blind bake for 15 minutes, then carefully remove the beans and parchment. Return to the oven for another 5-7 minutes until the pastry is golden and crisp. The base should look dry and feel firm to the touch. Trim any remaining overhanging pastry for a neat edge, then set aside to cool slightly. Reduce oven temperature to 170°C (150°C fan). </li> <li class="MethodStepper"> <h4 class="step-title">Step 9</h4> Pour the cooled custard into the pastry case, smoothing the surface with a spatula. Arrange the halved plums decoratively on top, cut side up, gently pressing them slightly into the custard. The plums will release their juices during baking, creating lovely pockets of tangy flavor that balance the creamy custard. </li> <li class="MethodStepper"> <h4 class="step-title">Step 10</h4> Bake for 25-30 minutes until the custard is set but still has a slight wobble in the center - it will continue to firm up as it cools. The custard should reach an internal temperature of about 75°C if you're using a food thermometer. The plums should be soft and their juices starting to caramelize slightly. </li> <li class="MethodStepper"> <h4 class="step-title">Step 11</h4> While the tart is cooling, prepare the glaze. Heat the apricot jam with the tablespoon of water in a small saucepan until melted and smooth. Pass through a sieve if necessary to remove any fruit lumps. While the tart is still warm, brush this glaze over the plums to create a beautiful sheen and to protect the fruit from drying out. </li> <li class="MethodStepper"> <h4 class="step-title">Step 12</h4> Allow the tart to cool completely before removing from the tin. The cooling process is crucial for the custard to set properly, so resist the temptation to cut into it while warm! Just before serving, dust lightly with icing sugar if desired. This tart is best enjoyed on the day it's made but will keep in the refrigerator for up to 2 days. Bring to room temperature before serving to allow the flavors to fully develop. </li> </ol>

Chef’s Notes

A few helpful details for making this recipe.

Why is my custard for fruit tarts not setting properly?

Custard may not set properly if it hasn't reached the correct temperature during cooking (around 75°C) or if there's insufficient cornflour. Always stir constantly until the mixture thickens enough to coat the back of a spoon, and ensure it cools completely before adding to your tart.

Can I use different fruits for a custard tart?

Absolutely! While plums offer a perfect balance of sweetness and tartness, you can substitute with other stone fruits like peaches, nectarines or apricots. Berries, poached pears or figs also work beautifully. Adjust the sugar in the custard depending on your fruit's sweetness.

How do I prevent a soggy bottom on my custard tart?

For a crisp base, thoroughly blind bake your pastry until golden and completely dry to the touch. Allow the custard to cool completely before filling the case, and if possible, add the custard just before serving. The cornflour in the custard also helps prevent excess moisture leaking into the base.
