Mix sugar, graham crumbs, and melted butter together in a small mixing bowl. Mix well and should be the consistency of wet sand.
Lightly grease a 9-inch spring-form cheesecake pan. Dump the crumb mixture into the bottom of the greased pan and press firmly. Set aside or in the freezer.
In a small sauce pan add chopped strawberries and sugar. Cook on medium heat for about 10-13 minutes. Mash the strawberries with a wooden spatula or spoon until you have a jam-like texture.
If you would like the sauce to have fewer chunks and be all the same texture you can also allow it to cool. Then run it through a blender. You can skip this if you don’t mind having strawberry chunks.
In a large mixing bowl with a hand mixer, mix cream cheese, sugar, and vanilla until well blended.
Add in the eggs and mix until fully blended. Make sure not to overbeat the eggs.
Next add in the sour cream and heavy cream, and starch. Mix until thoroughly blended. It should look like thick yogurt, not liquid.
Pour the cheesecake batter over the crust.
Pour strawberry sauce over the cheesecake filling. Feel free to do some swirls with a toothpick if you like.
Place the cheesecake pan into a water bath.
Bake in a water bath at 375F for 1 hour, or until the center is no longer liquid and just slightly jiggly. Turn off the oven and leave the cheesecake in with the door slightly ajar until the cheesecake has cooled to room temperature.
Once the cheesecake has cooled, cover and put it in the refrigerator and let it set overnight.
Before serving, slice some fresh strawberries and place them on the cheesecake.
