Jewels of pomegranate gelée decorate this colorful citrus tart, which is accented with both lemon and lime. The crunch of cornmeal in the crust provides a slightly sweet textural contrast to the creamy custard filling. Apply the gelée over the tart and then pepper it randomly with the pomegranate arils, or seeds. This tart is best served the day it is baked; refrigerate any leftovers.
To make the Pomegranate Gelée:
Pour the pomegranate juice into a measuring cup. Sprinkle the gelatin over the surface, and set aside for about 5 minutes to soften. Then pour into a small saucepan, add the sugar, and heat over low heat just to dissolve the gelatin and sugar. Do not allow to boil.
Remove from the heat and pour into an 8-inch round cake pan. The mixture should be 1/8 inch deep.
Cover and refrigerate until set, about 1 hour.
To make the pastry:
In a food processor, combine the flour, sugar, cornmeal, lemon zest, lime zest, and salt and pulse 3 or 4 times to blend.
In a small bowl, mix together the egg yolk and vanilla just to combine. Scatter the butter pieces over the flour mixture. Pulse using 1-second bursts until the mixture resembles a combination of bread crumbs and coarse meal, 15 to 20 seconds.
Add the egg yolk mixture and continue to pulse just until the ingredients come together.
Transfer the dough to a work surface. Beginning at the far end, and using the heel of your hand, push a small amount of the dough (about the size of an extra-large egg) away from you, smearing it on the work surface. Repeat with the remaining dough in small amounts.
When you’ve worked all the dough in this manner, give it a couple more strokes to bring it together into a smooth, homogeneous unit. (This kneading technique is known as fraisage.) Flatten the dough into a disk. Wrap in plastic wrap and refrigerate until chilled and slightly firm, at least 1 hour or up to 3 days.
Before baking: Center a rack in the oven and preheat the oven to 375 degrees F. Have ready a 9½ by 1-inch round fluted tart pan with a removable bottom.
Remove the dough from the refrigerator. If it is too firm to roll, let sit at room temperature until it is malleable enough to roll yet still cool to the touch, 15 to 30 minutes. Press the dough evenly into the bottom and up the sides of the tart pan. Or, roll out the dough on a lightly floured work surface into a 12-inch circle 1/8 to 3/16 inch thick. Roll up the pastry around the rolling pin, and suspend the pin about 1 inch above the pan. Aligning the edge of the dough with the rim of the pan farthest from you, unroll it toward you. Then gently fit the dough into the pan, easing it into the crevices and up the sides. Trim away the excess dough by rolling the pin over the top of the pan. (Save any scraps for another use, if desired.)
Bake the tart shell until it is pale gold and the surface no longer looks wet, raw, or shiny, 15 to 20 minutes.
Check after baking for about 5 minutes. If the pastry is puffed up, prick the center of the blistered area with a metal or wooden skewer or fork tines to release the steam. Don’t prick more than is needed. Transfer to a wire rack and let cool while you prepare the filling. Leave the oven on.
To make the Lemon Custard Filling:
In a medium bowl, beat the eggs with a fork just to combine. Add the sugar, lemon juice, and lime juice and mix just until blended. To remove any unincorporated egg to create a smooth filling, pour the mixture through a fine-mesh sieve set over another bowl. Stir in the cream slowly just until blended.
Place the tart pan on a rimmed baking sheet (to catch drips), and carefully pour the filling into the pastry shell. Place the tart on the baking sheet in the oven and bake until the filling appears set yet shiny on top, the center quivers a bit when the pan is gently shaken, and the edges of the crust are golden, 18 to 20 minutes.
Transfer to a wire rack and let cool on the pan for about 20 minutes. Set the tart pan on a narrower elevated surface, such as a tin can, so the bottom of the pan is released as the metal rim slips down. Return the tart to the wire rack and let cool to room temperature.
To serve: At least 30 minutes before serving, remove the gelée from the refrigerator. With the tip of a paring knife, cut lines about 1/8 inch apart in both directions (the pattern will look like graph paper) to form the pomegranate jewels.
With a wide metal spatula (similar to what you would use to turn pancakes), lift the gelée from the pan to break the cut pieces apart. Lift some of the pomegranate gelée onto the same spatula, and scatter the gelée over the lemon filling.
Then, scatter the pomegranate seeds over the top. Refrigerate the tart just long enough to chill the gelée pieces, about 30 minutes.
Cut the tart into wedges with a sharp knife.
To remove the seeds from a pomegranate, cut the crown end off the pomegranate, removing some of the white pith with it. Try not to pierce the seeds inside. Lightly score the rind (skin) in quarters, from the stem to the crown end. Firmly yet gently break the sections apart, following the score lines. Bend back the skin and gently scoop the seed clusters into a bowl, and then remove the pith.
