Combine chopped strawberries, granulated sugar, water, and cornstarch in a medium saucepan. Simmer over medium heat, stirring constantly and breaking up the strawberries as they soften, until juices release and sauce thickens, about 5 minutes.
02 -
Transfer the hot sauce to a fine mesh strainer set over a bowl and press through to remove seeds and solids. Allow the strained strawberry sauce to cool completely.
03 -
Preheat the oven to 190°C. In a medium bowl, combine graham cracker crumbs, granulated sugar, and melted salted butter, mixing until the texture resembles wet sand.
04 -
Press crumb mixture firmly into the base of a 25-centimeter springform pan. Bake for 7-8 minutes. Remove from the oven and allow the crust to cool while preparing the filling.

Break the white chocolate bar into pieces and place in a bowl. Melt in the microwave in 20-second increments, stirring between each, until smooth. Alternatively, melt gently over simmering water in a double boiler. Set aside to cool.

In a large mixer bowl, beat softened cream cheese and granulated sugar at medium speed until smooth and creamy, about 2 minutes.
07 -
Add sour cream and all-purpose flour to the cream cheese mixture, beating on low speed and scraping the sides and bottom of the bowl as needed.
08 -
Beat in eggs one at a time at low speed, scraping the bowl between additions. Avoid overbeating to minimize air incorporation.
09 -
Mix in vanilla extract and cooled, melted white chocolate until combined.

Pour half the cheesecake batter over the cooled crust. Dollop approximately 3 tablespoons of strawberry sauce over the batter. Pour in the remaining batter and top with another 3 tablespoons of sauce. Use the tip of a knife to gently swirl for a marbled effect.
11 -
Reduce oven temperature to 165°C. Place the pan on a rack in the lower two-thirds of the oven and bake for 65-75 minutes, until the edges are set but the center is slightly jiggly.
12 -
Turn off the oven and open the door. Allow the cheesecake to rest undisturbed for 10 minutes. After 10 minutes, run a knife around the inside edge to loosen it from the pan.
13 -
Let the cheesecake cool in the open, turned-off oven for an additional 1-2 hours. Transfer to the refrigerator and chill for at least 4 hours or overnight prior to serving.
