- 1 cup plus 2 tablespoons flour
- 1/4 cup sugar
- 1/4 teaspoon salt
- 7 tablespoons cold butter, cut into pieces
- 1 egg yolk
- 1 tablespoon ice water
- 2 large eggs, cold
- 2 large egg yolks, cold
- 3/4 cup sugar
- 1/2 cup fresh lemon juice
- 6 tablespoons (3 ounces) cold butter, cut into pieces
- Combine flour, sugar and salt in processor. Add butter; cut in using on/off turns until mixture forms coarse crumbs. Mix yolk and ice water in small bowl. Add to crumb mixture; process until dough begins to clump together. Press over bottom and up sides of 9-inch tart pan with removable bottom. Trim edges. Pierce crust all over with fork. Chill 30 minutes.
- Preheat oven to 350°. Line crust with foil. Fill with dried beans or pie weights. Bake until crust is set, about 20 minutes. Remove foil and beans. Continue baking until pale golden, pressing with back of fork if crust bubbles, about 20 minutes longer. Transfer crust to rack.
- Bring about 1½ inches of water to a boil in a pot that is slightly smaller than the diameter of the bowl you will be using for the filling. Meanwhile, in a large metal bowl, whisk the eggs, yolks, and sugar for about 1 minute, or until the mixture is smooth.
- Set the bowl over the pot and, using a large whisk, whip the mixture while you turn the bowl (for even heating…I didn’t do this; just whisked). After about 2 minutes, when the eggs are foamy and have thickened, add one-third of the lemon juice. Continue to whisk vigorously and, when the mixture thickens again, add another one-third of the lemon juice. Whisk until the mixture thickens again, then add the remaining lemon juice. Continue whisking vigorously, still turning the bowl, until the mixture is thickened and light in color and the whisk leaves a trail in the bottom of the bowl. The total cooking time should be 8 to 10 minutes.(mine took a lot longer….maybe 15-20…just make sure it has thickened)
- Turn off the heat and leave the bowl over the water. Whisk in the butter a piece at a time. The filling may loosen slightly, but it will thicken and set as it cools. Pour the warm filling into the tart crust and place the pan on a baking sheet.
- Serve at room temperature or cold. May garnish with whipped cream and raspberries if desired.
