Crust
Add the graham crackers to a food processor and crush them until they are fine.
Combine graham cracker crumbs with the sugar and the melted butter and process again.
Press the cracker crumbs into the springform pan and bake for about 10 minutes.
Allow the crust to cool while making the cheesecake.
Lower temperature on the oven to 325-degrees.
Cheesecake
Add the cream cheese to a large mixing bowl and cream for a few minutes, or until all the lumps are gone.
Add the sugar and cream again for about three minutes.
Next, add the salt and vanilla extract and mix together.
Now, add the eggs, one at a time, and mix for about 30 seconds after the addition of each egg.
Add the sour cream and mix until combined.
Finally, add the heavy cream and mix until combined.
Place three sheets of heavy duty aluminum foil underneath the graham cracker crust and gently press up against the sides and then press down around the top.
Pour the cheesecake mixture into the springform pan and place into a large roasting or large baking pan.
Boil some water.
Place the roasting pan with the springform pan, into the oven. Pour the boiling water to the side of the springform pan, so that water comes up about two inches around the springform pan.
Bake cheesecake for 1-1/2 hours.
Once the time is up, turn the oven off and leave the oven door open a few inches and let it cool off for about an hour.
Once the cheesecake cools, put it in the refrigerator for several hours or overnight.
