Preheat oven to 350°F (175°C). Pulse graham crackers, granulated sugar, and kosher salt in a food processor until finely ground. Add melted butter and pulse until evenly combined. Press mixture firmly into the base and up the sides of a 9-inch round tart pan with removable bottom.

In a clean food processor, blend cream cheese, sour cream, granulated sugar, egg, vanilla seeds or extract, and kosher salt just until smooth. Avoid overmixing to maintain creamy texture.

Refrigerate until thoroughly chilled, at least 2 hours or overnight for best texture.

Evenly sift 1 tablespoon superfine sugar over the surface of the chilled cheesecake, avoiding the crust. Using a small kitchen blowtorch, sweep flame back and forth to caramelize sugar, focusing on the center to prevent burning the crust. Repeat with remaining tablespoon superfine sugar for a second brûléed layer.
