Making a passionfruit cheesecake is a straightforward process. Follow these steps to achieve cheesecake perfection:

1. Preheat your oven to 325°F (163°C).
2. Prepare the crust:
   • Mix the crushed graham crackers and melted butter in a bowl.
   • Press the mixture firmly into the bottom of a 9-inch springform pan to form an even layer.
3. Prepare the cheesecake filling:
   • In another bowl, beat the cream cheese and sugar together until smooth and creamy.
   • Add the eggs one at a time, mixing well after each addition.
   • Stir in the vanilla extract and passionfruit pulp until fully incorporated.
4. Assemble the cheesecake:
   • Pour the cream cheese mixture over the prepared crust in the springform pan. Spread it evenly.
5. Bake the cheesecake:
   • Place the cheesecake in the preheated oven and bake for 45-50 minutes. The cheesecake should be set but still slightly jiggly in the center.
6. Cool and refrigerate:
   • Allow the cheesecake to cool at room temperature. Once cooled, refrigerate it for at least 4 hours to ensure it sets properly.
7. Finish with sour cream:
   • Before serving, spread a layer of sour cream over the top of the cheesecake for added creaminess and a slight tang.
