Rhubarb & ginger creme brûlée tarts: buttery pastry, creamy spiced custard, sharp rhubarb and a glassy caramelised surface. Jump to Recipe
Hello from week 1000 of stage 4 lockdown in Melbourne! While we watch the rest of Australia (and what seems like the world) enjoy the simple pleasures – albeit those that I will never take for granted again – of dinner parties with friends, flat whites out of an actual coffee cup, a restaurant meal not spooned from a takeaway container, walking through a lit up evening city – we remain at home. The news of our lockdown extension for essentially a further 6 weeks recently was devastating, even if not particularly surprising. And I get it! While surrounded by states and countries (hello new zealand) that have driven case numbers down to near zero, it will be impossible for borders with Victoria to open until we’ve also obliterated community transmission. Doesn’t mean it doesn’t hurt. And I realise I’m one of the very lucky ones still able to go to work – small businesses and hospitality are being crushed, with hardly any hope of reopening restaurants until at least December.
In the meantime, I’m also on 2 weeks of forced annual leave – hopes of an overseas adventure were initially reduced to thoughts of heading home to Auckland, or a possible beach trip to Byron Bay or Queensland (I think I was in denial for a while, ok), and has morphed into a strict 5km radius from home and an 8pm curfew. Copious amounts of sugar have been involved in maintaining sanity thus far – Ottolenghi’s dark chocolate & hazelnut babka and mini coffee & walnut friands, a dark chocolate coffee caramel slice that needs serious work, Tivoli Road Bakery’s vanilla custard morning buns, and the clear winner: these rhubarb and ginger creme brûlée tarts.
They’re inspired by a couple of different recipes – mostly clearly the infamous Bourke Street Bakery ginger brûlée tarts. I remember thinking it was possibly the best tart I’d ever eaten when I demolished one last year, sitting in 40 degree heat outside their Surrey Hills cafe before a day of walking Sydney and eventually collapsing on Manly beach with a book (adventures like these seem like a lifetime ago, don’t they?). I’ve also been enamoured by the rhubarb & lemon curd brûlée tart by another Sydney bakery, The Cook and the Baker, for a while – and couldn’t help but think they deserved a mash-up.
Don’t be put off by the number of steps – spread out over a couple of days, it’s very doable (and a great lockdown project, speaking from experience). I’ve used my most fool-proof, buttery and crisp sweet short pastry recipe – easiest made in a food processor but you can also make it by hand. The custard is a slightly lighter version from the original, using both cream and milk, and is infused overnight with fresh ginger, cardamom pods and a cinnamon quill. The trickiest step of the entire process is thickening the custard – you need to ensure it thickens enough to set before you make the tarts, without overheating it and causing it to split or curdle. Cooking it slowly and gently over low heat and stirring CONSTANTLY is your friend here. The rhubarb gets a quick turn in the oven with vanilla paste and sugar while the tart tins are blind baked. You assemble with cooled rhubarb, a dollop of custard, and break out your blow torch to brûlée the surface (very satisfying I promise). Buttery pastry, creamy spiced custard, sharp rhubarb and a glassy caramelised surface – it’s worth the effort.
Inspired by the ginger creme brulee tarts of Bourke Street Bakery.
They do take a couple of days to complete: infuse the custard 2 days before serving, and make the custard and the pastry the day before. Do the final steps of filling the pastry cases in the few hours prior to serving, and the brulee just prior to serving.
- 220 g plain flour
- 70 g icing sugar
- pinch of salt
- 145 g butter, refrigerator cold chopped into cubes
- 1 teaspoon vanilla essence
- 1 teaspoon white vinegar
- 1 egg yolk
- 1-2 tablespoons ice water if needed
- 360 ml pouring cream (also called double cream in the UK. NOT ‘thickened cream’ – in Australia this has extra additives.)
- 140 ml whole milk
- 4 cm piece ginger finely sliced
- 1 cardamom pod crushed
- 1/2 cinnamon stick
- 1 teaspoon vanilla paste or 1 vanilla bean halved lengthways
- 5 egg yolks
- 60 g caster sugar
- 40 g plain flour
- 500 g rhubarb
- 2 tablespoons caster sugar
- 1 teaspoon vanilla
- extra caster sugar for brûlée
- chopped pistachios to decorate
-
Combine the cream, milk, ginger, cardamom, cinnamon and vanilla in a heavy based saucepan, and bring to a simmer over a medium heat. Transfer into a bowl or container and refrigerate overnight to infuse.
-
The next day, place back in a medium saucepan and bring to a simmer again.
-
Strain the cream mix through a fine sieve to remove all the spices.
-
While the cream mixture comes to a simmer, whisk together the egg yolks and sugar in a medium sized bowl until pale. Add the flour and whisk until smooth and combined.
-
Slowly pour the strained cream over the egg mixture, whisking constantly as you go (to avoid cooking the eggs) until completely combined.
-
Return the custard mix to the saucepan over a low heat and whisk continuously to avoid burning or curdling. Use a spatula around the corners of the pan every 20-30 seconds to avoid it catching in the corners. It will take about 5-10 minutes to thicken and just start to bubble on the surface. You want it thick enough to hold a figure eight if you draw it with the whisk on the surface – like a thick pouring custard. As soon as this happens, pour directly into a clean bowl and whisk for 2 minutes to cool quickly. Lay a piece of plastic wrap over the surface to avoid a skin forming, then refrigerate the custard to cool it completel – overnight is ideal. It will keep for 3 days in the fridge.
-
You can make this pastry by hand but I find it is very easy to do in food processor if you have one and prevents the butter getting too soft.
-
Combine the flour, icing sugar and salt in the bowl of a food processor. Pulse on low speed to combine.
-
Add the cold butter cubes and pulse until the largest pieces of butter are just bigger than pea-size. Add the vanilla essence, white vinegar, egg yolk and a tablespoon of ice water. Pulse on medium speed just until the dough starts barely clumping together, 6-10 times. It will still be a bit crumbly but will stay together when you press it together with your fingers- do not over mix. Tip out onto a lightly floured surface and bring together with your hands into a disc. Wrap in cling film and refrigerate for at least 2 hours or overnight.
-
Grease 8 mini tart tins (mine were 10cm diameter). Roll out the pastry on a lightly floured bench to about 3mm thick and line the tart tins, pressing firmly into the sides of the tin. If too hard to roll, leave it at room temperature for 10 minutes to soften a little. If it rips at all or you find that one edge is too thin, it is easy to use the leftover pastry scraps to patch it back together.
-
Trim the pastry to form a neat edge – I usually roll my rolling pin over the edge to cut through the pastry.
-
Rest the lined tart tins in the freezer for at least 15 minutes or the fridge for 30min-1hr until firm.
-
Preheat the oven to 180°C. Line the pastry cases with foil, then fill with dry rice or pie weights and blind bake for 15 minutes. Remove the weights and foil, then return to the oven for a further 5 minutes, or until golden. Set aside to cool.
-
To roast the rhubarb: preheat the oven to 180°C. Wash the rhubarb and cut into 5cm lengths. Toss with the caster sugar and vanilla to coat. Line a baking tray with baking paper and lay out the rhubarb in a single layer. Roast for 10-15minutes until fork tender, then set aside to cool completely.
-
Distribute the cooled rhubarb between the bases of the cooked tart shells, avoiding taking the juices in the pan as they may make the pastry soggy after a while.
-
Top with the custard to fill the tart cases, using a small palette knife to spread flush with the edges of the tart tins. Refrigerate until ready to brûlée. This step is best done in the few hours prior to serving.
-
In the hour prior to serving, sprinkle the top of each tart with about 1/2 tbsp caster sugar in an even layer. Burn with a blowtorch to caramelise the top. Sprinkle chopped pistachios on top to serve.

Where can I buy these 10cm tart pans?
Claudia Brick says
Hi Susannah! You can usually get them online – I’m in Australia so I got them from Kakkadu here https://kakkadu.com.au/products/loose-base-fluted-quiche-pan-non-stick-10cm-diameter-x-2cm-deep?_pos=3&_sid=47398143a&_ss=r but there are lots of similar ones online
Susanna says
Thanks for your quick reply. I only have 8cm diameter ones so couldn’t add any rhubarb. Nevertheless these tarts were amazing!! Everyone loved them. Thanks for sharing the recipe.
Maggie Rutherford says
I just made these for the dessert for our Easter Sunday family dinner this weekend and I can tell you that they were a huge hit! Everyone loved them, they were the perfect mix of tangy rhubarb, sweet custard, and crispy tart shell. One of the most interesting desserts I’ve made in a while. Thank you for such a great recipe!
Claudia Brick says
Hi Maggie, that is so wonderful to hear! I am so glad everyone enjoyed. Thanks again for letting me know x
Natalie says
great recipe! Question: is the tart then served cold? And, would it be possible to serve it warm aswell?
Claudia Brick says
Hi Natalie! Yes they are served cold/room temperature, as the creme brûlée custard wouldn’t work so well at a higher temperature. The brûlée does warm it slightly though
