AND TO MAKE THE FILLING, FOLLOW THESE STEPS:

1st Step

Beat the softened cream cheese for two to three minutes, or until it is creamy and smooth, in a large mixing bowl.

2nd Step

Beat the cream cheese until thoroughly blended before gradually adding 1 1/2 cups of granulated sugar and the vanilla essence.

3rd Step

One at a time, add the eggs and mix on low speed just long enough to incorporate each one. Watch carefully not to combine too much.

4th Step

When the mixture is silky and creamy, combine the heavy cream and sour cream. Finally, blend just before adding the all-purpose flour and a dash of salt.

5th Step

Over the cooked graham cracker crust in the springform pan, pour the cheesecake filling. Once the borders are firm and the middle is somewhat wobbly, bake the pan at 300°F (150°C) for 60 to 70 minutes.
