Whisk cornstarch and cold water in a small bowl to create a slurry. Stir slurry into the simmering raspberry mixture and cook for an additional 2 to 3 minutes, stirring often until thickened. Remove from heat.
03 -
Pour the raspberry sauce through a fine mesh strainer into a bowl, using the back of a spoon to push the puree through while discarding seeds. Set aside to cool completely.

Preheat the oven to 350°F. Line the bottom of a 9-inch springform pan with parchment paper and spray the sides with cooking spray.
05 -
Mix graham cracker crumbs, granulated sugar, and melted butter in a medium bowl until combined. Press mixture firmly into the bottom and up the sides of the prepared pan. Bake for 10 minutes and cool.

Reduce oven temperature to 325°F. Wrap the outside of the springform pan tightly with two layers of heavy-duty aluminum foil to prevent water infiltration. Set aside.

In a stand mixer fitted with a paddle attachment, beat cream cheese on medium speed for 1-2 minutes until smooth and lump-free. Scrape down sides of the bowl.

Add granulated sugar and beat until combined. Reduce speed to medium-low, add eggs one at a time, beating gently after each addition to avoid aeration. Scrape bowl as necessary.
09 -
Mix in sour cream, heavy cream, fresh lemon juice, vanilla extract, and lemon zest just until combined. Scrape bowl walls and stir to ensure an even, smooth batter.

Pour batter evenly into the graham cracker crust, smoothing the surface. Tap pan gently against the counter to release air bubbles.
11 -
Fill a disposable piping or zip-top bag with about half to three-quarters of cooled raspberry sauce. Dot tablespoon-sized amounts over batter and swirl with a knife or skewer to create marbled patterns.

Place the foil-wrapped springform pan into a large roasting pan. Pour 4 to 5 cups of very hot water into the roasting pan until it reaches approximately 1 inch up the side of the springform pan.

Bake for 100 to 105 minutes. The center should jiggle slightly when the pan is gently moved. Turn off oven, crack door open 1 inch, and let cheesecake rest in oven for 1 hour.
