An overhead shot of a perfectly golden shortcrust tart filled with pale yellow lavender-infused custard, with tiny flecks of lavender buds visible throughout. The surface has a slight sheen catching the soft natural light streaming through a nearby window. Several tiny lavender sprigs decorate one edge, while a slice is being removed, revealing the smooth, set custard texture. The tart rests on a weathered wooden board alongside a vintage silver serving knife and a small bunch of fresh lavender. A fine dusting of icing sugar highlights the tart's delicate textured edge, creating a beautiful contrast against the deep purple of the lavender garnish.

Directions

<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Start by making the pastry. Place the flour, cubed cold butter and salt in a food processor and pulse until the mixture resembles fine breadcrumbs (or rub together by hand). The cold butter creates small pockets of fat that will steam during baking, creating flaky layers in your pastry.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Add the icing sugar and pulse briefly to combine. Add the egg yolk and enough cold water (1 tablespoon at a time) until the dough just comes together - be careful not to overwork it. Form into a disc, wrap in cling film and chill for at least 30 minutes to relax the gluten.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>While the pastry chills, prepare the lavender infusion. In a medium saucepan, combine the milk, lavender buds, and vanilla seeds with the pod. Heat gently until just below simmering point, then remove from heat, cover, and let steep for 20 minutes. This slow infusion extracts the floral flavor without bitterness.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Preheat your oven to 180°C (fan 160°C/350°F). Roll out the chilled pastry on a lightly floured surface to about 3mm thickness, large enough to line your tart tin. Carefully transfer to the tin, gently pressing it into the corners without stretching. Trim the excess and prick the base with a fork.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Line the pastry case with baking parchment and fill with baking beans or dried rice. Blind bake for 15 minutes, then remove the beans and parchment and bake for another 5-10 minutes until the base is pale golden and feels dry to the touch. Lower the oven temperature to 160°C (fan 140°C/320°F).</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>For the custard, strain the infused milk through a fine-mesh sieve to remove the lavender buds and vanilla pod. Return the strained milk to a clean saucepan and heat until just below simmering point. In a heatproof bowl, whisk together the egg yolks, caster sugar, and cornflour until smooth and pale.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Gradually pour the hot milk into the egg mixture, whisking constantly to prevent curdling. The slow addition tempers the eggs, preventing them from scrambling. Pour the mixture back into the saucepan and cook over medium-low heat, stirring constantly with a wooden spoon, until thickened enough to coat the back of the spoon (about 5-7 minutes).</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Pour the custard into the pre-baked tart shell. If any lumps formed, strain the custard first. Bake in the oven for 20-25 minutes until the custard is just set but still has a slight wobble in the center – it will continue to set as it cools. The custard should reach 75°C in the center when tested with a thermometer.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Allow the tart to cool completely in the tin, then refrigerate for at least 2 hours to fully set. The cooling process is crucial for the perfect custard texture - rushing this step can result in a runny filling.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>Just before serving, carefully remove the tart from the tin. Decorate with fresh lavender sprigs if desired and dust lightly with icing sugar. Serve chilled for the best flavor and texture. The tart keeps well refrigerated for up to 2 days, though the pastry will gradually soften.</li></ol>

Chef’s Notes

A few helpful details for making this recipe.

What's the secret to a perfectly set custard filling that doesn't crack?

The secret lies in proper temperature control. Bake the tart at a lower temperature (160°C/140°C fan) until the custard reaches 75°C in the centre, with a slight wobble remaining. Allow it to cool completely before refrigerating for at least 2 hours, as rushing this cooling process can lead to cracks.

How can I ensure the lavender flavour isn't overpowering in my custard?

Use only culinary-grade lavender (not ornamental) and stick to the recommended 2 tablespoons of dried buds. Infuse the milk for exactly 20 minutes—any longer risks bitterness. Strain thoroughly before proceeding, and balance with vanilla, which softens the floral notes while enhancing the custard's overall flavour.

Can I make this tart in advance for a dinner party?

Yes, this tart is perfect for preparing ahead. Make it up to two days in advance and store in the refrigerator. The flavour actually improves after a day as the lavender notes mature. Add the fresh lavender garnish and icing sugar dusting just before serving for the best presentation.
