Preheat the oven to 325°F (165°C).
In a bowl, mix graham cracker crumbs, melted butter, and 2 tablespoons of sugar until the mixture is well combined.
Pat this into the bottom of a 9-inch springform pan.
In a separate mixing bowl, mash the cream cheese until soft and creamy.
Gradually beat in sour cream, 3/4 cup sugar, flour, and vanilla extract.
Add the eggs one at a time, beating until just incorporated.
Pour the cream cheese mixture over the crust in the pan.
Bake for about 1 hour, or until the center is firm to the touch.
Once baked, transfer the cheesecake to the refrigerator and chill for at least 4 hours until thoroughly cold.
To serve, run a knife around the edge of the cheesecake, release the springform latch, and place the cheesecake on a serving platter.
Arrange frozen blueberries on top.
Melt the jelly over low heat in a saucepan and spoon it over the blueberries to glaze.
Chill again until ready to serve.
