Classic French Fruit Tart, Gluten Free

Instructions

1. 1

   Mix the pastry dough

   Pulse the gluten-free flour blend, xanthan gum, powdered sugar, almond flour, and salt together in a food processor. Scatter the cold butter cubes over the top and pulse in short bursts until the mixture looks like coarse sand with a few pea-sized butter pieces. Whisk the egg yolk with the vanilla, drizzle it in, and pulse until the dough starts clumping. Gluten-free blends drink up liquid unevenly, so expect to add 1 to 2 teaspoons of cold water — the dough should squeeze into a cohesive ball, not crumble apart. There's no gluten to overdevelop here, so mix until it's genuinely uniform.

2. 2

   Shape and chill

   Gather the dough into a disc about an inch thick and wrap it tightly. Refrigerate for at least 1 hour and up to overnight. This rest matters more in the gluten-free version than the wheat one: the rice flour and starches need time to fully absorb moisture, and a dough that goes in gritty comes out of the fridge smooth, pliable, and far less prone to cracking.

3. 3

   Line the pan

   Roll the dough between two sheets of parchment into an 11-inch round about 1/8 inch thick. If it cracks at the edges as you roll, pinch the cracks closed and keep going. Invert it over a 9-inch fluted tart pan with a removable bottom and ease it in. If the round tears on transfer, don't start over — simply press the dough into the pan in pieces and smooth the seams with your fingertips, since gluten-free dough patches invisibly and bakes seamlessly. Trim the rim, prick the base all over, and freeze the shell for 30 minutes.

4. 4

   Blind bake the shell

   Heat the oven to 350°F (175°C). Line the frozen shell with parchment and fill it to the top with pie weights. Bake for 20 minutes, then remove the parchment and weights and bake another 15 to 18 minutes. Gluten-free shells need a few extra minutes and a deeper color than you'd expect — look for golden brown all the way across the base, not just at the edges, because an underbaked gluten-free crust stays pasty rather than crisp. Cool completely in the pan.

5. 5

   Start the pastry cream

   Warm the milk in a medium saucepan over medium heat until steam rises and small bubbles ring the edge. Meanwhile, whisk the sugar, cornstarch, and salt together in a bowl, then whisk in the yolks and keep whisking for about 30 seconds, until the mixture loosens into a smooth, pale ribbon.

6. 6

   Temper and thicken

   Pour about a third of the hot milk into the yolks in a thin stream while whisking constantly, then whisk that mixture back into the pan. Cook over medium heat, whisking into the corners the whole time, until it thickens suddenly and large bubbles break the surface. Let it bubble a full 60 seconds to cook out the raw starch taste and keep the cream from thinning later. Off the heat, whisk in the butter and vanilla bean paste.

7. 7

   Strain and chill the cream

   Press the pastry cream through a fine-mesh sieve into a clean bowl, lay plastic wrap directly on the surface, and refrigerate at least 3 hours, until cold and firmly set. Whisk it smooth and glossy again just before using.

8. 8

   Fill the shell

   Set the cooled shell on a serving plate and remove the outer ring. Whisk the cold pastry cream until creamy, then spread it into the shell in an even layer with an offset spatula, flush with the top edge.

9. 9

   Arrange the fruit

   Pat the fruit completely dry, then arrange it over the cream in concentric rings from the outside in, overlapping slightly so no cream peeks through. Drying the fruit is doubly important here — gluten-free crusts soften faster from below once moisture reaches them.

10. 10

    Glaze and serve

    Warm the apricot jam with the water until fluid and strain out the solids. Brush it lightly over the fruit, chill the tart 30 minutes to set the glaze, then slice with a thin sharp knife, wiping the blade between cuts. Serve the same day for the crispest crust.

Baker's Tips

• 1.

  Split the work across two days: shell and pastry cream one day, assembly the next. Both keep well separately, but the assembled tart is best within hours.

• 2.

  Pie weights need to reach the top of the shell, not just cover the base. A half-filled shell is exactly how you end up with slumped, shrunken sides.

• 3.

  If the baked shell has a hairline crack, brush the inside with a little melted white chocolate and let it set before filling. It seals the crack and doubles as moisture-proofing.

• 4.

  Strawberries, blueberries, raspberries, blackberries, kiwi, and thin pear or peach slices all hold their shape well. Skip anything that browns fast, like banana or apple, unless you glaze it immediately.

• 5.

  No vanilla bean paste? Use the same amount of good vanilla extract, stirred in off the heat so the flavor doesn't cook away.

• 6.

  If your pastry cream turns lumpy, keep whisking vigorously over the heat — most lumps work out, and the sieve catches the rest.
