For the Crust
1-1/2 cups graham cracker crumbs, from 12 whole crackers
5 tablespoons unsalted butter, melted
1/8 teaspoon salt
For the Filling
32 oz (four 8-oz blocks) cream cheese, at room temperature
1 1/2 cups sugar
3 tablespoons all-purpose flour
4 teaspoons vanilla extract
1 teaspoon packed lemon zest, from 1 lemon
2 teaspoons fresh lemon juice, from 1 lemon
1/4 teaspoon salt
6 large eggs
1/2 cup sour cream
Special equipment: 9- or 10-inch springform pan; 18-inch heavy-duty aluminum foil (could add plastic from a baking bag to ensure water doesn't leak into the cake.
For the Crust
- Preheat the oven to 375°F and set an oven rack in the lower middle position. To make slices easier to remove, you can also add a piece of parchment paper to the bottom (Just measure and cut it into a round). Wrap a 9- or 10-inch springform pan with one large piece of heavy-duty aluminum foil, covering the underside and extending all the way to the top so there are no seams on the bottom or sides of the pan. Repeat with another sheet of foil for insurance.Spray the inside of the pan with nonstick cooking spray.
- Make the crust: In a medium bowl, combine the graham cracker crumbs, melted butter, and salt. Stir until well combined.
- Press the crumbs into an even layer on the the bottom of the prepared pan. Bake the crust for 10 minutes, until set. Remove the pan from the oven and set aside.
- Reduce the oven temperature to 325°F. Boil some water for the pan where the cheesecake will sit.
For the Batter:
- Make the batter: In the bowl of an electric mixer fitted with the paddle attachment or beaters, beat the cream cheese, sugar, and flour together on medium speed until just smooth, about 1 minute. Scrape the bottom and sides of the bowl to be sure the mixture is evenly combined. Add the vanilla, lemon zest, lemon juice, and salt; beat on low speed until just combined. Add the eggs, one at a time, mixing on low speed until incorporated, scraping the bowl as necessary. Mix in the sour cream. Make sure the batter is uniform but do not over-mix.
- Check to make sure your oven has cooled to 325°F, then set the cheesecake pan in a large roasting pan. Pour the batter on top of the crust. Pour the boiling water into the large roasting pan to come about 1 inch up the side of the cake pan.
- Bake until the cake is just set, 1 hour and 30 minutes to 1 hour and 45 minutes (the cake should not look liquidy at all but will wobble just a bit when the pan is nudged; it will continue to cook as it cools). Carefully remove the roasting pan from the oven and set it on a wire rack.
- Cool the cheesecake in the water bath until the water is just warm, about 45 minutes. Remove the springform pan from the water bath and discard the foil. If necessary, run a thin-bladed knife around the edge of the cake to make sure it's not sticking to the sides (which can cause cracks as it cools), then cover with plastic wrap and transfer to the refrigerator to cool for at least 8 hours or overnight.
- For serving: Remove the sides of the springform pan. Serve the cheesecake right from the base of the pan; or, to transfer it to a serving platter, run a long, thin spatula between the crust and the pan bottom, and then use two large spatulas to carefully transfer the cheesecake to a serving dish. Slice with a sharp knife, wiping the knife clean between slices. Serve with berry sauce, if you like.
- Make Ahead: The cheesecake can be made and stored in the springform pan in the fridge, tightly covered with plastic wrap, up to two days ahead of time.
- Freezer-Friendly Instructions: The cheesecake can be frozen for up to 3 months. To freeze, place the cake in the freezer briefly, unwrapped, to firm it up. Then double-wrap it tightly with aluminum foil or plastic freezer wrap, or place it in heavy-duty freezer bag. Thaw in the refrigerator the night before you plan to eat it.
