Wrap the outside of a 9-inch springform pan with aluminum foil, ensuring that the bottom and sides are covered tightly. Lightly grease the inside with non-stick cooking spray.
To make the crust mix together the graham crumbs, sugar and melted butter. Then press into the bottom of the pan and place in the freezer.
In a large bowl beat together the cream cheese and sugar until very soft.
Then beat in the eggs one at a time. Then mix in the lemon zest, lemon juice and sour cream with the mixer on low.
Remove the crust from the freezer and place inside a large roasting pan. Pour the cheesecake batter into the springform pan on top of the crust. Then pour about 1/2 inch of water into the roasting pan.
Place the whole thing in the oven and bake for 50-60 minutes or until the top is no longer shiny and there’s a little wobble in the center of the cheesecake.
Cool at room temperature for 30 minutes, then cover and refrigerate for at least 4 hours or overnight.
