Begin the filling:


Step 1

In a medium bowl, whisk 1/3 cup of the sugar and the cornstarch, kosher salt, lemon zest, and vanilla extract. Add the plums and gently toss with your hands to evenly coat with sugar. Cover the bowl and put it in the refrigerator for at least 3 hours or overnight.

Step 2

Make the tart shell:

Step 3

Lightly butter the bottom and sides of a 9-1/2-inch fluted tart pan with a removable bottom.

Step 4

Put the butter cubes in the freezer.

Step 5

In a small bowl, whisk the egg yolk, lemon zest, and vanilla.

Step 6

Put the flour, sugar, and table salt in the bowl of a food processor and pulse a few times to combine. Add the butter and pulse until the mixture is crumbly and mealy, about 25 short pulses. Add the egg yolk mixture and blend, using long pulses, just until it forms a moist, crumbly mass, about 15 three-second pulses. The dough won’t come together on its own, but it should hold together when squeezed.

Step 7

Transfer the dough to the tart pan. Dip the bottom of a flat-bottomed cup measure in flour and use it to press the dough onto the bottom and sides of the pan in an even layer. Start with the sides, which should be 1/4 inch thick. Re-flour the cup whenever it starts to stick to the dough. Wrap the pan in plastic and refrigerate it for at least 1 hour and up to 1 day.

Blind bake the shell:


Step 8

Position a rack in the lower third of the oven and heat the oven to 375°F.

Step 9

Unwrap the tart shell and prick the bottom and sides several times with a fork. Spray one side of a piece of parchment or foil with cooking spray. Line the shell with the sprayed side down and fill the lined shell with pie weights or dry beans. Set the tart pan on a baking sheet and bake for 20 minutes. Carefully remove the liner and pie weights. Should any dough stick to the liner, simply peel it off and patch it back into the shell.

Step 10

Reduce the heat to 350°F and continue baking until the sides and bottom of the shell are golden brown and dry, 10 to 15 minutes more. Cool on a rack for about 20 minutes.

Finish the Tart:


Step 11

Drain the plums in a sieve or colander set over a medium bowl for a few minutes. Pour the juice into a small saucepan and bring to a simmer over medium heat.

Step 12

Reduce the heat to low and simmer, stirring occasionally, until very thick, about 3 minutes. Scrape into a small bowl and let cool for about 10 minutes.

Step 13

Meanwhile, melt the preserves in the saucepan over medium-low heat until syrupy. Pour the preserves into the tart shell and evenly brush them over the bottom and sides. With a rubber spatula, spread the plum juice over the preserves on the bottom of the shell.

Step 14

Starting at the edge of the shell, arrange the plum slices cut side down and tightly overlapping in concentric circles. If you have more slices, keep tucking them in wherever they fit. You can also pile a few in the center of the tart.

Step 15

If any juice remains in the mixing bowl, drizzle up to 1 Tbs. over the plums. Discard the rest. Sprinkle the remaining 1/2 Tbs. sugar over the plums.

Step 16

Bake the tart directly on the oven rack until the plums are tender when poked with a paring knife and caramelized along their edges (a few tips may even blacken), the crust is a deep golden brown, and any juices look syrupy and bubbly, 40 to 50 minutes. After you remove the tart from the oven, moisten the plums by dipping a pastry brush into the juices between the plums and brushing any surfaces that look dry.

Step 17

Cool the tart in its pan on a rack for at least 2 hours before unmolding and slicing with a very sharp knife.

Make Ahead Tips: You can toss the plums with the sugar mixture and chill the unbaked tart shell up to a day in advance.
