Pastry Cream for Fruit Tarts
A proper fruit tart relies on a base that won't soak through your crust or slide off the fruit. This custard is the structural foundation that holds your layout in place.
Watch the heat and keep whisking.
The margin between thickened custard and scrambled eggs is slim; stay at the stove and use a heavy-bottomed pan to prevent scorching.

What goes in.
- 2 cupswhole milk
- 1/2 cupgranulated sugar
- 4large egg yolks
- 3 tbspcornstarch
- 2 tbspunsalted butter, room temperature
- 1 tspvanilla extract
Gradual Heat Introduction
Slowly adding hot milk to your cold egg mixture prevents the yolks from curdling, ensuring the final cream is silky rather than grainy.
The method.
Heat the milk
Bring the milk to a bare simmer in a saucepan over medium heat, then remove from the burner.
Whisk yolks and sugar
In a separate bowl, whisk the yolks, sugar, and cornstarch until the mixture is pale yellow and thick.
Temper the eggs
Whisking constantly, drizzle about half of the hot milk into the egg mixture to bring them up to temperature, then pour everything back into the saucepan.
Cook to thicken
Return the pan to medium heat. Whisk continuously until the mixture bubbles. Once it thickens into a heavy paste, cook for one more minute to remove the raw cornstarch taste.
Strain and cool
Pass the cream through a fine-mesh sieve into a clean bowl. Stir in the butter and vanilla, then press plastic wrap directly onto the surface to prevent a skin from forming.
Other turns to take.
Lemon Cream
Whisk in two tablespoons of fresh lemon zest and three tablespoons of lemon juice after removing the pan from the heat.
Chocolate Variation
Stir in four ounces of chopped bittersweet chocolate while the custard is still hot to create a dense, ganache-like filling.
When it doesn't go to plan.
Always place a piece of plastic wrap directly touching the top of the custard while it cools to stop a thick, rubbery skin from developing.
If you see small lumps, do not panic—pass the cream through a sieve a second time to smooth it out.
Wait until the custard is completely cold before pouring it into a pre-baked tart shell; if it is still warm, the residual heat will soften your crust.
The ones that keep coming up.
Can I use flour instead of cornstarch?
You can, but it requires longer cooking to remove the floury taste and the texture will be slightly less transparent and glossy than one thickened with cornstarch.
How long will this stay firm in the fridge?
Once fully chilled and set, the tart will hold its texture for 24 hours. After that, moisture from the fruit or the custard may start to soften the pastry shell.
