Blood Orange Tarts with Custard

I was arranging citrus at the farmers market when I spotted them: blood oranges with their deep crimson flesh peeking through split rinds. The vendor sliced one open and the juice ran like wine across the wooden table. I bought six on impulse, no plan in mind, just the certainty that something beautiful needed to happen with them. By that evening, my kitchen smelled like butter and vanilla, and those tarts were cooling on the counter, almost too pretty to eat.

I made these for a dinner party once where half the guests were late and I was convinced the tarts would sit too long and weep. But they held beautifully in the fridge, custard firm and shells still crisp when we finally sat down at nine. Everyone went quiet after the first bite, then someone asked if I'd trained in France. I laughed and said no, just a food processor and a little patience.

Ingredients

• All-purpose flour: The foundation of your tart shell, it needs to be measured correctly (spoon and level, never scoop) or the dough gets tough and hard to roll.
• Powdered sugar: Dissolves seamlessly into the dough and gives the crust a tender, melt-in-your-mouth texture that granulated sugar just cant match.
• Unsalted butter, cold and cubed: Cold butter creates those flaky layers, so cube it fast and get it back in the fridge if your kitchen is warm.
• Egg yolk: Adds richness and binds the dough without making it wet, one yolk is all you need for this amount of flour.
• Ice water: Use it sparingly, adding just enough to bring the dough together, too much and youll end up with a sticky mess.
• Whole milk: The custard base, whole milk is essential here because lower fat versions wont give you that luxurious, creamy texture.
• Granulated sugar: Sweetens the custard just enough to balance the tang of the blood oranges without overpowering them.
• Egg yolks: These thicken the custard and give it that pale yellow glow, make sure theyre fresh for the smoothest result.
• Cornstarch: Insurance against curdling, it stabilizes the custard so you can whisk with confidence over heat.
• Pure vanilla extract: A teaspoon transforms the custard from plain to perfume, use the real stuff if you can.
• Blood oranges: The star of the show, look for firm fruit with deep color and avoid any that feel spongy or dry.
• Honey: Optional but magical, it adds shine and a hint of floral sweetness that makes the oranges glisten like stained glass.

Instructions

Make the Tart Dough:

Pulse the flour, powdered sugar, and salt in your food processor until combined, then add the cold butter and pulse until the mixture looks like wet sand. Add the egg yolk and pulse again, drizzling in ice water one tablespoon at a time just until the dough clumps together when you pinch it.

Chill the Dough:

Shape it into a flat disk, wrap it tightly in plastic, and let it rest in the fridge for at least an hour. This relaxes the gluten and makes rolling out so much easier.

Roll and Shape:

On a floured surface, roll the dough to about 1/8 inch thick, then cut circles large enough to fit your tart pans with a little overhang. Press gently into each pan, trim the edges, and chill again for 20 minutes so they hold their shape in the oven.

Blind Bake the Shells:

Line each shell with parchment, fill with pie weights or dried beans, and bake at 350°F for 15 minutes. Remove the weights and parchment, then bake another 5 minutes until the bottoms turn golden and crisp.

Cook the Custard:

Heat the milk in a saucepan until it steams, then whisk together the yolks, sugar, and cornstarch in a bowl until smooth and pale. Slowly pour the hot milk into the yolk mixture while whisking, then return everything to the pan and cook over medium heat, stirring constantly, until it thickens and bubbles.

Finish and Chill the Custard:

Pull the pan off the heat, stir in the vanilla and butter until melted, then transfer to a bowl and press plastic wrap directly onto the surface to prevent a skin. Let it cool to room temperature, then refrigerate for at least an hour.

Prepare the Blood Oranges:

Peel the oranges carefully, removing as much white pith as you can, then slice them into thin, even rounds. Pat them gently with a paper towel to remove excess juice so they dont make the custard watery.

Assemble the Tarts:

Spoon the chilled custard into each cooled tart shell, smoothing the top with the back of a spoon. Arrange the blood orange slices on top in overlapping circles, starting from the outside and working in.

Glaze and Serve:

If you want that professional sheen, warm the honey and water together in a small pan, then brush it lightly over the orange slices. Chill the tarts until youre ready to serve, they taste best cold and hold beautifully for several hours.

The first time I served these, my friend who claims she doesnt like dessert ate two. She said it was the contrast, the way the tart orange woke up the sweet vanilla, and how the crust added just enough crunch to keep things interesting. I realized then that this wasnt just a tart, it was a little conversation on a plate, each element saying something the others needed to hear.

Choosing Your Blood Oranges

Not all blood oranges are created equal. The best ones feel heavy for their size and have smooth, thin skin with a slight give when you press gently. I learned to avoid any with soft spots or a dull, dry appearance, those tend to be past their prime and lack the juicy brightness you want. If blood oranges arent in season or you cant find good ones, regular navel or cara cara oranges work beautifully, you just lose that dramatic ruby color.

Making the Custard Foolproof

Custard has a reputation for being fussy, but the cornstarch in this recipe is your safety net. It stabilizes the eggs so you can cook the mixture a little hotter without worrying about curdling. I used to tense up every time I made pastry cream, but once I started trusting the whisk and keeping the heat at medium, it became second nature. If you do see any lumps, just strain the custard through a fine mesh sieve before chilling and no one will ever know.

Storing and Serving Tips

These tarts are at their absolute best when assembled no more than a few hours before serving. The custard stays creamy, the shells stay crisp, and the oranges stay bright. If you need to make them a day ahead, store the components separately and put them together that morning.

• Keep baked shells in an airtight container at room temperature for up to two days.
• Store custard in the fridge, covered, for up to three days, and give it a quick whisk before using.
• Slice the oranges the morning of serving and keep them covered in the fridge so they dont dry out.

Every time I pull these tarts from the fridge and see those jewel-toned oranges against the pale custard, I remember why I fell in love with baking in the first place. Its not just about following steps, its about turning something simple into something that makes people stop and smile.

Recipe Q&A

→ Can I make these tarts ahead of time?

Yes, you can prepare the tart shells and custard a day in advance. Store them separately in the refrigerator and assemble just before serving to maintain the crisp texture of the pastry.

→ What can I substitute for blood oranges?

Regular oranges, cara cara oranges, or even grapefruit work well as substitutes. You can also use a mix of citrus fruits for a colorful presentation.

→ How do I prevent the custard from becoming lumpy?

Whisk constantly while cooking and ensure you temper the egg yolks by gradually adding the hot milk. Strain the custard through a fine-mesh sieve if any lumps form.

→ Can I freeze the tart shells?

Yes, baked tart shells freeze beautifully for up to 3 months. Wrap them individually in plastic wrap and store in an airtight container. Thaw at room temperature before filling.

→ How long will assembled tarts keep?

Assembled tarts are best enjoyed within 24 hours. The pastry may soften over time due to the custard, so assemble close to serving time for optimal texture.

→ Do I need special tart pans?

Individual 4-inch tart pans with removable bottoms work best for easy release and presentation. Alternatively, you can use a single 9-inch tart pan and adjust baking time accordingly.
