In a small saucepan over medium heat, add strawberries, sugar, cornstarch, water, and lemon juice.
Cook until thickened, stirring constantly.
Once the sauce has thickened, let cool then spoon mixture on top of the cheesecake in different places.
Next, take a toothpick or knife and swirl the strawberry sauce around to achieve a swirl effect.
Place cheesecake on aluminum foil and wrap the foil up around the sides.
Place in a shallow pan or roasting pan.
Add hot water halfway up the cheesecake pan (this helps the cheesecake from cracking).
Bake for 1 hour and 10 minutes or until the center is almost set and still a little jiggly.
Carefully remove from the oven and let the water cool enough in the roasting pan before removing the cheesecake, then set the cheesecake on a wire rack to cool. Once cool enough, place in the refrigerator and chill for 4+ hours or overnight.
