Lemon Curd Tart
- 1 rolled-out round of Basic Tart Dough
- 3 whole eggs plus 3 egg yolks, lightly beaten
- 3/4 cup sugar
- 3/4 cup fresh lemon juice, strained (about 6 large lemons)
- 2 Tbs. finely grated lemon zest
- 12 Tbs. (1 1/2 sticks) unsalted butter, cut into 1⁄4-inch cubes
- Sweetened whipped cream for piping
Meanwhile, position a rack in the lower third of an oven and preheat to 375°F.
Line the pastry shell with aluminum foil or parchment paper and fill with pie weights or raw short-grain rice. Bake for 20 minutes, then lift an edge of the foil. If the dough looks wet, continue to bake, checking every 5 minutes, until the dough is pale gold, for a total baking time of 25 to 30 minutes. Remove the weights and foil. Continue to bake until the shell is golden, 7 to 10 minutes more. Transfer to a wire rack and let cool completely.
In a nonaluminum saucepan over medium heat, combine the eggs, egg yolks, sugar, lemon juice, lemon zest and butter. Cook slowly, stirring constantly with a heatproof rubber spatula, until the butter melts and the mixture is thick enough to coat the back of the spatula and leaves a clear trail when a finger is drawn through it, 7 to 8 minutes. Remove from the heat and strain through a coarse-mesh sieve placed over a bowl.
Spread the curd evenly in the fully baked tart shell and refrigerate until chilled, 2 to 3 hours. Using a pastry bag fitted with a small star tip, pipe whipped cream around the edge of the tart. If using a tart pan with a removable bottom, let the sides fall away, then slide the tart onto a serving plate. Let stand at room temperature for 20 minutes before serving, to take the chill off. Makes one 9 1/2-inch tart; serves 8.
