01 - Preheat oven to 320°F (160°C). Line the base of a 9-inch springform pan with parchment paper.
02 - Combine finely crushed graham crackers and melted butter. Press mixture firmly into the prepared pan. Chill in refrigerator while assembling the filling.
03 - Beat cream cheese until smooth using an electric mixer. Add granulated sugar and mix thoroughly. Add eggs one at a time, blending after each addition. Incorporate sour cream and vanilla extract. Stir in passion fruit pulp until evenly mixed.
04 - Pour the filling over the chilled crust and smooth the surface. Bake for 45–50 minutes, or until the center is mostly set with a slight wobble. Turn off oven and leave cheesecake to cool inside with the door slightly ajar for 1 hour.
05 - Remove cheesecake from oven. Cool to room temperature, then cover and refrigerate for at least 4 hours or overnight until thoroughly chilled.
06 - Combine passion fruit pulp, water, and sugar in a small saucepan over medium heat. Dissolve cornstarch in a splash of cold water, then whisk into the pan. Bring to a boil, stirring constantly until thickened and glossy. Remove from heat and cool briefly.
07 - Once cheesecake is completely cold, spread the glaze evenly over the surface. Return to refrigerator for 20 minutes to set the glaze before serving.
