Prepare the Crust: In a mixing bowl, combine the graham cracker crumbs and melted butter until evenly moistened. Press the mixture firmly into the bottom of a 9-inch springform pan. Refrigerate while preparing the filling.
Bloom the Gelatin: In a small bowl, sprinkle the gelatin powder over cold water. Let it sit for about 5 minutes until it blooms (absorbs the water and softens).
Make the Filling: In a large mixing bowl, beat the softened cream cheese and powdered sugar together until smooth. Add sour cream, lemon juice, lemon zest, and vanilla extract; mix until well blended.
Incorporate the Strawberries: Gently fold in the pureed strawberries into the cheesecake mixture until fully combined.
Melt the Gelatin: Heat the bloomed gelatin mixture in the microwave for about 10-15 seconds until it’s completely dissolved. Then, slowly stir it into the cheesecake mixture, ensuring it’s well incorporated.
Pour and Chill: Pour the cheesecake batter over the chilled crust, smoothing the top with a spatula. Cover with plastic wrap and refrigerate for at least 4 hours or until fully set (preferably overnight).
Serve: Once set, carefully remove the sides of the springform pan. Garnish the top of the cheesecake with fresh strawberries and lemon slices before slicing into wedges.
Notes
For best results, refrigerate overnight to allow the cheesecake to fully set.
