Although this cheesecake is not often made, well you can see from the ingredients, this is your best shot at giving it a try if you ever wanted to. It is a thicker cheesecake that is just as creamy and delicious.
You will need:
5 large eggs, room temperature
2 cups sour cream, room temperature
4 8-ounce packages cream cheese, room temperature
8 tablespoons (one stick) unsalted butter, room temperature
1 1/ 2 cups sugar
2 tablespoons cornstarch
1 1/ 2 teaspoons vanilla extract
1 teaspoon fresh lemon juice
1 teaspoon grated lemon zest
Generously butter the inside of a 10-inch spring form pan. Wrap a double layer of heavy-duty aluminum foil tightly around the outside bottom and sides, crimping and pleating the foil to make it conform to the pan. This will help to prevent water seeping into the pan when you put it into the bain-marie. Position the baking rack in the centre of the oven; preheat the oven to 300º Fahrenheit. In a large mixing bowl, using an electric mixer, beat the eggs with the sour cream until well blended. In a medium-sized bowl, beat the cream cheese with the butter until smooth and creamy. Add this to the egg-sour cream mixture and beat until smooth. Add the sugar, cornstarch, vanilla, lemon juice and lemon zest and beat thoroughly, about 2 minutes. Pour into the prepared spring form pan and place in a roasting pan (or other pan) large enough to prevent the sides from touching. Place in the oven and carefully pour in enough very hot tap water to reach halfway up the sides of the spring form pan. Bake for 2 hours, 15 minutes, or until the cake is very lightly coloured and a knife inserted in the centre emerges clean. Remove from the water bath and carefully peel the aluminum foil from around the pan. Let stand at room temperature until completely cool, about 4 hours. Refrigerate, covered, until well chilled. For best flavour and texture, this cheesecake is best chilled overnight.
