Blueberry Custard Tart: A Slice of Summer

My grandmother, bless her heart, wasn’t much of a baker. But she had one recipe, clipped from a magazine decades ago and stained with the ghosts of blueberries past, that she made every summer when the berries were plump and bursting with flavor. It wasn’t fancy, but her Blueberry Custard Tart, served slightly warm with a dollop of whipped cream, was pure sunshine on a plate. It evokes memories of lazy afternoons on her porch, the scent of warm pastry mingling with the sweet aroma of ripening berries in the summer air. Now, armed with her beloved recipe, I am honored to share this simple masterpiece with you.

Instructions

1. Prepare the Pastry: Lightly flour the ball of pastry. Flatten it into a 6 or 7-inch circle. Place it on a floured pastry cloth.
2. Roll the Dough: With a floured rolling pin, roll the pastry until it forms a circle about 13 ½ to 14 inches in diameter. It’s important to keep the dough the same thickness all over, even though it will become very thin. This ensures even baking and a sturdy crust.
3. Transfer to Tart Pan: Transfer the dough to the tart pan, centering it carefully.
4. Shape the Crust: Quickly ease the dough on the sides down into the pan, making the sides a little thicker to prevent slumping during baking.
5. Trim the Edges: Using scissors, trim the edges, leaving an even ½ to ¾ inch border standing up over the rim of the pan.
6. Create the Rim: Fold in a narrow hem, about ¼ inch wide, folding toward the middle (not toward the outside) and leaving the rim of the pastry raised a bit above the edges of the pan. This creates a decorative edge and helps contain the filling.
7. Decorate the Rim (Optional): With pastry pincers, form a design on the rim. Alternatively, with the dull side of a knife blade, form shallow ridges on an angle to decorate it.
8. Dock the Crust: Prick fork holes about ½ inch apart in the bottom of the pastry. This prevents the crust from puffing up during baking.
9. Chill the Crust: Place the tart pan in the freezer for at least 15-20 minutes. Chilling the crust helps prevent it from shrinking during baking.
10. Preheat the Oven: Adjust a rack one-third up from the bottom of the oven and preheat to 400°F (200°C).
11. Blind Bake: Center a 12-inch square of foil, shiny side down, over the frozen shell. Press the foil into place in the shell, and fill it with dried beans or pie weights.
12. First Bake: Bake for 15 minutes.
13. Remove Foil & Weights: Remove the shell from oven and slowly/gently remove the foil by raising all four corners at once.
14. Second Bake: Return the shell to the oven; bake for 5-10 minutes, until it is dry and the bottom barely begins to color. Remove shell from oven and cool for about 10 minutes.
15. Reduce Oven Temperature: Decrease oven temperature to 325°F (160°C).
16. Prepare the Filling: Wash and thoroughly dry the blueberries; set aside. Excess moisture can make the crust soggy.
17. Combine Dry Ingredients: Sift together the sugar, cinnamon, and nutmeg; set aside. Sifting ensures even distribution of the spices.
18. Combine Wet Ingredients: In a large bowl, beat the eggs and egg yolks lightly just to mix; stir in the dry ingredients, vanilla, and cream. Avoid over-beating, which can incorporate too much air.
19. Assemble the Tart: Place the blueberries evenly in a layer in the prepared pastry shell.
20. Add Custard: Gently and slowly pour part of the cream mixture over the berries. Do not fill the shell all the way or it might spill on the way to the oven.
21. Settle the Berries: With the back of a large spoon, tap any berries that are on top of the custard just to wet the tops a bit. This prevents them from burning during baking.
22. Bake the Tart: Place the pan in the oven, then reach in and pour in the remaining custard (if there are any low spots on the rim of the pastry, the custard will run over; watch it carefully and , if necessary, do not use the full amount.
23. Check for Doneness: Bake for about 35 minutes, until the custard no longer shakes if you tap the pan, and until a small sharp knife gently inserted into the middle of the custard comes out clean.
24. Cool Completely: Let the tart cool to room temperature. This allows the custard to set properly.
25. Remove from Pan: Remove the sides of the pan by placing the pan on a shallow custard cup; the sides will slip down.

Expert Tips & Tricks

• For an extra-crisp crust, brush the cooled, blind-baked crust with a thin layer of melted white chocolate or egg white before adding the filling. This creates a moisture barrier.
• If your crust edges brown too quickly during baking, cover them with foil strips.
• If the custard starts to brown too quickly, reduce the oven temperature slightly or tent the tart loosely with foil.
• Make the pastry dough a day in advance and chill it thoroughly. This allows the gluten to relax, resulting in a more tender crust.

Serving & Storage Suggestions

Serve the Blueberry Custard Tart at room temperature or slightly chilled. A dollop of freshly whipped cream or a scoop of vanilla ice cream makes a delightful accompaniment.

Leftovers can be stored in the refrigerator for up to 3 days. Cover the tart loosely with plastic wrap to prevent it from drying out. While you can freeze the tart, the texture of the custard may change slightly upon thawing. Reheat gently in a preheated oven at 300°F (150°C) until warmed through.

• Almond Extract: Replace the vanilla extract with almond extract for a nutty twist.

FAQs (Frequently Asked Questions)

Q: Why do I need to blind bake the crust?
A: Blind baking ensures that the crust is fully cooked and crisp before adding the wet filling, preventing a soggy bottom.

Q: Can I use frozen blueberries?
A: Fresh blueberries are best for this recipe, but frozen blueberries can be used in a pinch. Be sure to thaw them completely and drain off any excess liquid before adding them to the tart.

Q: How do I prevent the custard from cracking?
A: Avoid overbaking the tart. The custard should be set but still slightly jiggly in the center when you remove it from the oven.

Q: My crust shrunk during baking. What did I do wrong?
A: Shrinking crusts are often caused by insufficient chilling or overworking the dough. Make sure to chill the dough thoroughly before baking and handle it as little as possible.

Q: Can I make this tart ahead of time?
A: Yes, you can bake the tart a day in advance and store it in the refrigerator. The flavor will even improve overnight!
