Step 1

Preheat the oven to 350 degrees Fahrenheit.

Step 2

Crush up your graham cracker pieces in a blender or food processor till a nice fine crumb is formed.

Step 3

Mix the crumbs, melted butter and sugar together.

Step 4

Press into the bottom and slightly up the sides of a 9 in springform sprayed with pam.

Step 5

Wrap foil around the bottom of the pan and around the sides over the top.

Step 6

Bake for about 8 - 10 minutes. Allow to cool as you prepare the blueberry sauce and filling.

Step 7

Put the blueberries and sugar together in a small saucepan over medium heat.

Step 8

In a small bowl mix together the lemon juice, cornstarch and water.

Step 9

Add the cornstarch to the blueberries, smashing some of the berries as you stir it together. Remove from heat as the mixture starts to thicken.

Step 10

Push through a fine mesh strainer to separate the juice and the berries. Save both for later.

Step 11

Add in the eggs, one at a time, mixing after each addition till just blended.

Step 15

Pour the filling into the cooled crust.

Step 16

Drop the blueberry sauce (not the berries) on the top of the batter. You'll use about 1/4 cup of it here. Mix the extra sauce back in with the cooked berries and save for later.

Step 17

Use a knife to gently swirl the blueberry sauce around the top of the cheesecake in a marbled fashion.

Step 18

Place the pan into a large roasting pan, or deep cookie sheet filled with 1/2 to 1 inch of hot water.

Step 19

Bake for 55-65 minutes until the center is almost set, except for a couple inches in the middle.

Step 20

Open the oven door slightly and leave the cheesecake in there for 1 hour.

Step 22

Cover and place in the fridge overnight.
