Lemon Curd Marbled Cheesecake
Ingredients
For lemon curd:
- 1 teaspoon finely grated fresh lemon zest
- 1/2 cup fresh lemon juice
- 1/2 cup sugar
- 3 large eggs
- 1/2 stick (1/4 cup) unsalted butter, cut into small pieces
For crust:
- 1 1/3 cups finely ground graham cracker crumbs (5 oz)
- 1/3 cup sugar
- 1/8 teaspoon salt
- 5 tablespoons unsalted butter, melted
For filling:
- 3 (8-oz) packages cream cheese, softened
- 1 cup sugar
- 3 large eggs
- 3/4 cup sour cream
- 1 teaspoon vanilla
- Special equipment: a 9- to 91/2-inch (24-cm) springform pan
- Accompaniment: blueberries
Make lemon curd:
Whisk together zest, juice, sugar, and eggs in a 2-quart
heavy saucepan. Add butter and cook over moderately low heat, whisking
frequently, until curd is thick enough to hold marks of whisk and first
bubbles appear on surface, about 6 minutes.
Force lemon curd through a fine-mesh sieve into a wide
shallow dish, scraping bottom of sieve, then cover surface with wax
paper. Cool completely, stirring occasionally, about 30 minutes.
Make and bake crust:
Put oven rack in middle position and preheat oven to
350°F. Invert bottom of springform pan (to make it easier to slide cake
off bottom), then lock on side. 3Stir together crust ingredients in a
bowl, then press onto bottom and 1 inch up side of springform pan. Place
springform pan in a shallow baking pan and bake 10 minutes, then cool
crust completely in springform pan on a rack.
Make filling and bake cheesecake:
Reduce oven temperature to 300°F.
Beat together cream cheese and sugar in a bowl with an
electric mixer at medium speed until smooth, 1 to 2 minutes. Reduce
speed to low and add eggs 1 at a time, beating until incorporated. Beat
in sour cream and vanilla until combined.
Pour two thirds of cream cheese filling into crust, then
spoon half of lemon curd over filling and swirl curd into filling with a
small knife. (Avoid touching crust with knife to prevent crumbs getting
into filling.) Repeat with remaining filling and curd.
Bake cheesecake until set 1 1/2 inches from edge but
center trembles when pan is gently shaken, about 45 minutes. (Center of
cake will appear very loose but will continue to set as it cools.)
Transfer springform pan to a rack and immediately run a knife around top
edge of cake to loosen. Cool completely, about 2 hours, then chill,
uncovered, at least 4 hours. Remove side of springform pan before
serving.
Cooks' Notes:
·Lemon curd can be made 1 week ahead and chilled, covered.
·Crust (without filling) can be made 1 day ahead and kept, covered, at room temperature.
·Cheesecake can be chilled, loosely covered, up to 2 days. Cheesecake
must be completely chilled before covering to prevent condensation on
its surface.
This is truly a wonderful cheesecake.
