Rainbow Cheesecake

Ingredients:
Crust
2 cups finely crushed graham crackers
2 tablespoons sugar
1/2 teaspoon ground cinnamon
1 pinch salt
6 tablespoons unsalted butter, softened
Filling
4 packages (8 oz each) cream cheese, room temperature
1 1/3 cups sugar
2 teaspoons vanilla
1 pinch salt
1 cup sour cream
1 cup heavy cream
4 large eggs
1 each of liquid food colors (blue, yellow, green, red)

Method:

1. Preheat oven 350 degrees. Before you get started with the crust, make sure your 9 inch springform pan is water tight. I do this by carefully wrapping a few layers of foil on the outside of the pan, so water cannot get into the pan. Be careful not to rip the foil or water will get into your cake and ruin it!
2. Mix crushed crackers, 2 tablespoons sugar, the cinnamon and salt together in a bowl. Then mix in butter with your clean fingers, until crumbs are pea sized. 
3. Press all of the graham cracker mixture into the prepared springform pan. Press it down firmly in the pan. I like to use a measuring cup for this, which makes it easy to get around the edges. You should have an even, flat crust.
4. Bake the crust for 10 minutes on a low oven rack. Remove from the oven, and cool completely before continuing. Turn oven temperature down to 325 degrees.
5. To make filling, cut cream cheese into pieces and add to a mixing bowl. Whip until smooth, maybe 4 minutes. Then add 1-1/3 cups sugar, and continue to beat until smooth again, another 4-5 minutes. Next, add vanilla, salt, sour cream and heavy cream; beat until smooth. Add in 1 egg at a time, beating briefly between each egg. 
6. Once the mixture is well combined and very smooth, divide evenly into 6 dishes. Add food color to each dish to get the desired colors. (Red = 25 drops of red, Orange = 18 drops yellow + 6 drops red, Yellow = 18 drops yellow, Green = 18 drops green, Blue = 18 drops blue, Violet = 18 drops red + 12 drops blue)
7. Pour colored mixtures into cooled crust. Start with red filling, and slowly pour it right in the center of the crust. Continue to build the rainbow by pouring the fillings directly in the center. This will create layers so that each slice has some of each color.
8. Place cheesecake into a baking dish on oven rack, and fill baking dish with boiling water about 1 inch up the side of the springform pan.
9. Bake at 325 degrees in the water bath for 1 hour and 40 minutes to 1 hour 50 minutes or until set but still jiggles slightly 2 inches from the edge. If cheesecake begins to brown on top, cover loosely with foil during last 5 minutes of baking.
10. Turn off the oven, open the oven door a crack, and let the cake cool in the oven for 1 hour. The slow cooling will help it not crack.
11. Then loosely wrap the dish in foil so the foil isn't touching the top of the cake and refrigerate for at least 4 hours.
12. When ready to remove cake, run a clean narrow knife around the edge of the dish, remove the foil, unlock the spring, and carefully lift off the outer ring.
13. Serve either alone or with a cherry/raspberry sauce. It's so rich and creamy that it really doesn't need a topping.
