I'm sharing this because frankly, it needs to be shared for everyone who can eat it. Seriously - so amazingly good. I'm not even talking about it more than this, just sharing.
Cooking Debauchery's cheesecake
EDIT: Sadly, this website is no longer with us. But thankfully, I copied the recipe itself because it was so awesome, so I'll share this genius' awesome cheesecake with others so it will not be lost.
"Best cheesecake ever
Adapted from Cook’s Illustrated
2 pounds cream cheese (4 8 oz packages), softened
4 eggs, room temperature
1/3 cup Kifir Cheese 
1 ¼ cups sugar
1 tablespoon vanilla
Zest of one small lemon, finely chopped
Butter and additional sugar for the pan
Pre-heat oven to 500 degrees.
Set oven to middle rack and slide into it a large roasting pan. Fill the bottom of the pan with boiling water and allow to heat with the oven to create a little steam. Bring another pot of water to a boil.
Removed the bottom of a 9 inch spring form pan. Line it with a large piece of tin foil, folding the edges under so that they do not interfere. Replace the bottom of the spring form pan into the hoop and lock into place. Carefully uncurl the tin foil from the bottom and bring it up around the edges of ring, crumpling at the top to create a water tight seal.
Brush the insides of the pan with melted butter making sure to coat every nook and cranny. Once the pan is coated, pour in 3 tablespoons sugar, shaking it around to evenly coat the bottom and sides. This will prevent the cheesecake from sticking.
Evenly distribute the cream cheese in the food processor. Turn to on and slowly add the sugar through the feed tube until the cream cheese loosens and becomes smooth. You might have to scrape down the sides a couple of times. Add eggs one at a time, scrapping down the sides between each addition if necessary.
Stop the processor. While it is stopped add the zest, vanilla and kifir cheese. Pulse until smooth and thoroughly combined.
Pour the batter into the prepared crust , resisting the urge to lick the mixer bowl. Shake the pan, taping it against the kitchen counter to get out any errant air bubbles.
Place into the middle of the roasting pan and add enough water to come up a little more than half way up the sides.
Bake at 500 degrees for 12 minutes.
Open the oven door and reduce the temperature to 200 degrees. Keep the oven door open for a few minutes until it cools slightly. Close the oven door and bake without opening for 1 hour.
The cheesecake will look done at this point and be jiggly in the center. It will want to come out. Don’t you believe it! To prevent cracks, run a thin knife between the edge of the cheesecake and the pan. It should retract readily. Close the door and bake for another hour to 75 minutes or until the whole cheesecake move in a slightly rubbery way when gently shaken.
Bring the temperature up to 350 and bake until the top is golden and puffed.
Remove to a wire rack and cool, tearing away the tinfoil to allow heat to escape.
Chill in the refrigerator over night. DO NOT be tempted to cut into it right away. This is very hard, I know, but the texture will not right until it has chilled thoroughly.
 Cheesecake Nirvana is currently located in my freezer where it will sit and await my birthday on the 16th.  Kifir Cheese is sometimes called Lebnan and can be found in Persian or Arabic markets. If kifir cheese is not available, substitute with Greek Yogurt, preferably drained for a few hours in a coffee filter.  The first hint I had that I was on the right track is that this cheesecake was nearly half an inch shorter than the cheesecake mousse horror! The pan should be about half full, maybe a little more.
