1. Prepare the Crust

• Preheat the oven to 325°F (163°C).

• Combine graham cracker crumbs, sugar, and melted butter in a bowl. Stir until the mixture is well-combined.

• Press the mixture into the bottom of a 9-inch springform pan, creating an even crust layer.

• Bake for 10 minutes, then remove from the oven and set aside to cool.

2. Prepare the Raspberry Swirl

• Cook raspberries, sugar, and lemon juice in a small saucepan over medium heat for 5-7 minutes until the raspberries break down and release their juice.

• Add the cornstarch slurry and cook for an additional 1-2 minutes until the mixture thickens.

• Strain the raspberry sauce through a fine sieve to remove the seeds, then set it aside to cool.

3. Make the Cheesecake Filling

• Beat the softened cream cheese and sugar together in a large bowl until smooth and fluffy.

• Add eggs one at a time, mixing gently after each addition to prevent overmixing.

• Mix in the sour cream and vanilla extract, then fold in the melted white chocolate until fully combined and smooth.

4. Assemble and Swirl

• Pour half of the cheesecake batter into the prepared crust.

• Spoon half of the raspberry sauce over the top of the batter, then swirl gently with a knife to create the raspberry swirl effect.

• Repeat with the remaining cheesecake batter and raspberry sauce, swirling again to create the desired pattern.

5. Bake in a Water Bath

• Wrap the bottom of the springform pan with aluminum foil to prevent leaks.

• Place the pan in a larger roasting pan and pour hot water halfway up the sides of the springform pan, creating a water bath.

• Bake for 55-70 minutes at 325°F, or until the cheesecake is just set with a slight jiggle in the center.

• Turn off the oven, crack the oven door, and let the cheesecake sit for 1 hour to cool gradually.

6. Chill and Serve

• Remove the cheesecake from the water bath and allow it to cool to room temperature.

• Refrigerate the cheesecake for at least 4 hours or overnight to allow it to set fully.

• Garnish with white chocolate curls and fresh raspberries before serving to add a beautiful touch.
