Lemon-Curd Strawberry Tart
1/2 cup Sugar
5 tablespoons Unsalted butter, cut into bits
2 lrg Eggs, beaten lightly
1/4 cup Fresh lemon juice
2 tablespoons Freshly grated lemon zest
1 1/2 cups All-purpose flour
6 tablespoons Confectioners' sugar
1 stk cold unsalted butter, cut into bits (1/2 cup)
3 tablespoons Sour cream
1 lrg Egg yolk
1/8 teaspoon Vanilla
1 1/2 pints Small strawberries, (about 18), hulled
1/4 cup Heavy cream
Make lemon curd:In a metal bowl set over a saucepan of simmering water cook sugar, butter, eggs, lemon juice, and zest, whisking frequently, until curd is thick enough to hold marks of whisk and the first bubble appears on surface, 12 to 15 minutes. Strain curd through a sieve into a bowl and cool. Chill curd, covered, until ready to use. Lemon curd may be made 1 week in advance and kept covered and chilled.
Make shell:In a food processor pulse flour, confectioners' sugar, butter, and a pinch of salt until mixture resembles coarse meal. In a small bowl stir together sour cream, egg yolk, and vanilla until combined well and add to flour mixture. Process mixture until a ball of dough is formed. Shape dough into a thick disk and chill, wrapped in plastic wrap, at least 30 minutes.
Preheat oven to 375F.
Assemble tart:Spread lemon curd evenly on shell, leaving a 1-inch border, and arrange strawberries on it. The tart may be assembled up to this point 3 hours in advance and kept covered.
