Base: Combine crushed crackers and melted butter. Press firmly into an 8-inch springform pan and chill.

Creaming: Beat cream cheese and sifted powdered sugar on medium speed for 3 minutes until perfectly smooth.

Combine: Slowly mix in the cooled melted white chocolate, vanilla bean paste, and fresh lemon juice on low speed until smooth.

Whip: In a clean bowl, whip cold heavy cream to medium-soft peaks.

Fold: Gently fold the whipped cream into the cream cheese batter in three parts using a spatula to keep it aerated.

Fill: Pour the smooth filling over the cold crust and level the surface cleanly with an offset spatula.

Chill: Cover and refrigerate for a minimum of 6 hours (ideally overnight) to allow the structural fats to set firm.

Slice: Rim the edges with a warm knife, unmold the springform pan, slice cleanly with a hot knife, and serve.
