- All ingredients must be at room temp. Blend cream cheese, sour cream and butter. 
- Add cornstarch, sugar, vanilla and lemon juice. Beat until well-blended. 
- Beat in one egg at a time, continuing to beat until mixture is light and smooth. 
- Pour into well greased 9” springform pan. (Place the pan on a large square of aluminum foil, and bring the foil up around the sides tightly to prevent water seeping in during baking.) Place the filled pan in a larger pan containing warm water to come halfway up the sides of the springform pan. 
- Bake at 375° for one hour until the top is golden and center is fairly firm. Turn oven off and let cake cool in it with door open for a least one hour. 
- Allow to stand at room temp to cool completely about 2 hours. Then cover and refrigerate several hours. About 20 minutes before serving, take out of refrigerator, remove ring and place on cake platter.
