Ingredients for French Style Custard Tart

• Graham Cracker crumbs - I used 10 full sheets of graham crakcers, but you are more than welcome to use store bought Graham cracker crust.
• Granulated Sugar - This is not an overly sweet tart, but we do need some sugar here.
• Unsalted Butter - Melted butter to make delicious custard filling.
• Whipping Cream
• Egg Yolks - What makes custard so yummy and rich is egg yolks. Don't be surprised that there are 9 of them in this recipe.
• Nutmeg - It's a popular spice for enhancing desserts, especially those with a creamy or dairy base, like our custard. Why? It adds a warm, nutty and slightly sweet flavor to our tart.
• Berries - Blueberries and raspberries are obvious choices because they are small and compact, I also like to use more rare fruits an berries as decoration.

Berry Custard Tart Components

The tart crust is a simple mixture of graham cracker crumbs, melted butter and sugar. It comes together quickly in a food processor and gives the tart great texture and flavor.

The filling is made from egg yolks, whipping cream and powdered sugar. It has a distinct flavor, due to the addition of nutmeg. The egg yolk mixture is thick and creamy, yet isn't overly sweet, which I love. Once the filling is added to the crust and baked, it sets in the fridge for a minimum of one hour. This ensures clean slices during serving.

To decorate, the tart is topped with fresh raspberries and blueberries, and garnished with  fresh mint.

How to make berry custard tart

Preheat oven to 350°F. and place Graham Crackers in a food processor, or smash in a sealed plastic bag until crumbs.

Make crust

Stir together the Graham Cracker crumbs, Sugar and Butter, and mix until all the crumbs are moist.

Press the mixture into the bottom and up the sides of an un-greased 9-inch fluted tart pan with a removeable base. A spoon and measuring cup work well. Bake for 7 minutes and then set aside.

French style custard filling

In a medium size saucepan bring the cream to a boil over medium low heat.

• Whisk the yolks and sugar together, then drizzle in a little hot cream, stirring well. Slowly pour in the remaining cream, whisking vigorously.
• Cook custard an additional 3 or 4 minutes on medium low heat.
• Strain the custard through a fine sieve into a bowl.

Assemble and bake

• To assemble the tart, pour in the strained custard into the crust, filling it to the brim, and sprinkle Nutmeg over the top.
• Bake for 30-40 minutes, or until the custard appears set, but not too firm (a little jiggly in the center).
• Remove tart from oven and allow to cool. Place in fridge and chill about 2 hours, or overnight, until firm.

When the tart filling is set, decorate as desired. Slice, and enjoy!

Expert Tips

Beginners often overcook custard or use too high heat, which leads to curdled or grainy texture. A smooth, creamy custard tart relies on gentle heat, constant stirring, and controlled baking. Following these steps helps avoid curdling, cracks, and soggy pastry, ensuring a silky, evenly set filling.

• Work fast: You need to pour the egg mixture quickly so you can stick it in the oven immediately. Otherwise , the pastry dough is slowly soaking up the egg liquid before it even start baking
• Use the lower third of your oven and also do a long preheat. This helps prevent the top from over baking and makes sure your pastry cooks all the way through.
• Custard is ready when it jiggles. Custards should be removed from the oven when they have that jello jiggle. If it still ripples when you nudge the pan it's too early, and if they puff up they went too long.
• Set your timer. I would also suggest always setting your timer for less than your recipe recommends. That way if they aren't baking quite evenly, you have time to rotate the pan and adjust the bake time.

Common Mistakes When Making Custard Tarts

• Using Too High Heat: Cooking custard over high heat causes the eggs to curdle, leading to a grainy or scrambled texture. Always use low to medium heat and keep whisking to maintain even temperature distribution and prevent curdling.
• Adding Eggs Too Quickly: Pouring eggs directly into hot milk without tempering leads to instant curdling. Gradually whisk warm milk into the eggs first, then combine back into the pan while stirring constantly to create a uniform, smooth mixture.
• Undercooking or Overcooking: Undercooked custard will be runny and fail to set properly, while overcooked custard becomes rubbery or cracks. The ideal custard should jiggle slightly in the center when removed from the oven, finishing its set as it cools.
• Neglecting Constant Stirring: For stovetop or partially cooked custards, constant whisking is critical to prevent scorching and ensure even thickening. This keeps the mixture glossy and lump-free.
• Thick or Undercooked Pastry: In custard tarts such as Pastéis de Nata, pastry that's too thick or underbaked prevents full crispness and can leave a soggy base. Roll dough thin (around 1-2 mm), blind bake if needed, and let it rest before filling.
• Overfilling Custard:Filling cases too high leads to spills and uneven baking. For best results, fill tart shells about three-quarters full to allow room for custard expansion during baking.

FAQ

• My custard is too foamy, what did I do wrong? I assume you overworked the custard (foamy texture) and didn't properly temper the eggs, resulting in an unstable mix.
• Should I whisk by hand? Yes hand whisking rather than machine in order to avoid overworked custard. If you over cook the custard they will dome and then dip down.
• Why Did My Custard Crack While Baking? Cracks form when the tart is baked too long or at too high a temperature. Bake just until the center jiggles slightly-overbaking dries out the custard and ruins that creamy finish.
• How to Keep the Crust from Getting Soggy: If moisture from the custard seeps into the crust, it softens. Blind-bake your graham cracker base for a few minutes to seal it and cool completely before pouring in the filling.
• Why Is My Custard Tart Runny? A runny texture means the custard didn't set fully. Check oven calibration and bake until the edges are firm but the center still wobbles slightly. The filling continues to set as it cools.
• How to Prevent a Scrambled Egg Texture High heat can cook the yolks too quickly. Always temper the eggs by slowly drizzling hot cream into the yolks while whisking, instead of dumping it in all at once.
• Can I Make It Ahead Without Ruining the Texture? Yes! This tart actually tastes better chilled overnight. Bake, cool, then refrigerate uncovered for 1-2 hours before loosely covering-this prevents condensation on the surface.

How to Store French Style Berry Custard Tart

Refrigerator: Store your custard tart in the refrigerator, covered loosely with plastic wrap or foil, for up to 3-4 days. Because the filling is cream- and egg-based, it must be kept cold at all times. Place it on a flat surface to prevent the custard from cracking or weeping overnight.

Pro tip: Wait until the tart is completely cool before covering-it prevents condensation from dripping onto the surface.

Can You Freeze Custard Tart?

Custard tarts don't freeze well because the silky custard tends to separate and become watery once thawed. If you must freeze it, wrap individual slices securely in plastic wrap, then foil, and freeze for up to 1 month. Thaw overnight in the fridge and serve chilled.

Alternative: Freeze just the graham cracker crust ahead of time for up to 3 months-then prepare and bake the custard fresh when you're ready.
