Lemon Curd Topping for Cheesecake

A vanilla wafer cookie crust works well with this variation of cheesecake.

1/3 cup juice (from about 2 lemons)
2 large eggs plus 1 large egg yolk
1/2 cup (3 1/2 oz.) sugar
2 tablespoons cold butter, cut into 1/2-inch cubes
1 tablespoon heavy cream
1/4 teaspoon vanilla extract
pinch of salt

While the cheesecake is baking, make the lemon curd. Heat the lemon juice in a small pan over medium heat until it is hot, but not boiling. In a small bowl, whisk the eggs. Gradually whisk in the sugar. Whisking constantly, slowly pour the hot lemon juice into the egg mixture, then pour the mixture back into the pan. Continue to cook over medium heat, stirring constantly, until the mixture reaches 170°F, or until it is thick enough to coat the back of a spoon. Remove the pan from the heat and whisk in the butter until it is melted. Stir in the cream, vanilla and salt. (If you have lumps in the curd, pour through a fine mesh strainer to strain any lumps.) Pour the curd into a small nonreactive bowl. Cover the surface of the curd directly with plastic wrap and refrigerate until needed.

When the cheesecake is cool, top it with the lemon curd while still in the springform pan. Cover tightly with plastic wrap and refrigerate for at least 5 hours, but 24 hours is better.
