Equipment

<ul class="equipment-main-list"> <li class="equipment-single-item">23cm (9-inch) tart tin with removable bottom</li> <li class="equipment-single-item">Food processor</li> <li class="equipment-single-item">Microplane or fine grater</li> <li class="equipment-single-item">Citrus juicer</li> </ul>

Directions

<ol class="no-list-style"> <li class="MethodStepper"> <h4 class="step-title">Step 1</h4> Preheat your oven to 180°C (160°C fan). Place a baking sheet in the oven to heat up – this will help ensure the bottom of your tart crust bakes evenly without becoming soggy. </li> <li class="MethodStepper"> <h4 class="step-title">Step 2</h4> For the crust, pulse digestive biscuits in a food processor until they form fine crumbs. Add the desiccated coconut and pulse briefly to combine. The coconut adds wonderful texture and flavor that complements the lime filling perfectly. </li> <li class="MethodStepper"> <h4 class="step-title">Step 3</h4> In a medium bowl, mix the biscuit-coconut mixture with melted butter, sugar, and salt until thoroughly combined. The mixture should hold together when pressed between your fingers – if it seems too dry, add a little more melted butter. </li> <li class="MethodStepper"> <h4 class="step-title">Step 4</h4> Press the mixture firmly and evenly into your tart tin, covering the bottom and sides. Use the back of a measuring cup to compact the crust – this prevents it from crumbling later. Prick the base several times with a fork to prevent air bubbles forming during baking. </li> <li class="MethodStepper"> <h4 class="step-title">Step 5</h4> Bake the crust on the preheated baking sheet for 10-12 minutes until lightly golden and fragrant. The pre-baking ensures your crust remains crisp even after adding the wet filling. Remove from oven and let cool slightly while preparing the filling. Reduce oven temperature to 160°C (140°C fan). </li> <li class="MethodStepper"> <h4 class="step-title">Step 6</h4> For the filling, whisk together eggs and sugar in a large bowl until pale and slightly thickened. This incorporates air into the custard, helping it set with a silky texture. </li> <li class="MethodStepper"> <h4 class="step-title">Step 7</h4> Add the lime zest, lime juice, coconut cream, and melted butter to the egg mixture, whisking until smooth and well combined. The acid in the lime juice will begin to thicken the mixture slightly – this is perfectly normal. </li> <li class="MethodStepper"> <h4 class="step-title">Step 8</h4> Place your tart tin with the pre-baked crust on the preheated baking sheet. Pour the filling into the crust – it should come almost to the top. If your crust has shrunk slightly during pre-baking, be careful not to overfill. </li> <li class="MethodStepper"> <h4 class="step-title">Step 9</h4> Carefully transfer to the oven and bake for 25-30 minutes until the edges are set but the center still has a slight wobble when gently shaken. The custard will continue to set as it cools – overbaking will cause it to crack, so watch carefully in the final minutes. </li> <li class="MethodStepper"> <h4 class="step-title">Step 10</h4> Remove from the oven and allow to cool completely at room temperature (about 2 hours) before refrigerating for at least 3 hours, preferably overnight. This cooling time is crucial for the custard to set properly and develop its flavors. </li> <li class="MethodStepper"> <h4 class="step-title">Step 11</h4> Just before serving, sprinkle the toasted coconut flakes over the top of the tart, add a little fresh lime zest for color, and dust lightly with icing sugar if desired. The toasted coconut adds wonderful texture contrast to the smooth custard. </li> <li class="MethodStepper"> <h4 class="step-title">Step 12</h4> To serve, carefully remove the tart from the tin and place on a serving plate. For clean slices, dip a sharp knife in hot water and wipe dry before each cut. The tart will keep refrigerated for up to 3 days, though the crust may soften slightly over time. </li> </ol>

FAQs

What ingredients are used in Lime Coconut Custard Tart?

This tropical tart requires digestive biscuits, desiccated coconut, butter, eggs, sugar, fresh limes (both juice and zest), coconut cream, and toasted coconut flakes for garnish. The combination creates a perfect balance of tangy citrus and creamy coconut flavours.

How to cook Lime Coconut Custard Tart at home?

Learn how to cook Lime Coconut Custard Tart by first creating a coconut-infused biscuit base that's pre-baked until golden. Then prepare a tangy lime custard with coconut cream, pour it into the cooled crust, and bake until just set with a slight wobble. After chilling thoroughly, top with toasted coconut flakes for a professional-looking dessert with tropical flavours.

Can I make this tart gluten-free without compromising texture?

Yes! Simply substitute the digestive biscuits with gluten-free digestive biscuits or a mixture of gluten-free oats and nuts processed with coconut and butter. The coconut in the crust already helps with binding, so the texture remains deliciously crumbly yet firm.

How do I prevent my citrus custard from curdling during baking?

To prevent curdling, ensure your oven temperature isn't too high (160°C is ideal), add the lime juice gradually while whisking, and never overbake. The tart is ready when the edges are set but the centre still has a slight wobble—it will continue setting as it cools.

What's the best way to achieve perfectly toasted coconut flakes for the topping?

For perfectly toasted coconut, spread flakes in a single layer on a baking sheet and bake at 160°C for 3-5 minutes, checking and stirring frequently. Alternatively, toast in a dry frying pan over medium heat, stirring constantly until golden. Watch carefully—coconut can burn quickly!
