Method
Step-by-Step
- Heat the oven to 175°C conventional, 160°C fan, or 350°F. Line the base of a 23 cm / 9-inch springform pan with baking parchment.
- Combine the rhubarb, sugar, lemon juice, and cornstarch in a saucepan. Cook over medium heat for 8–12 minutes, stirring occasionally, until the rhubarb softens and the juices thicken; stir in the vanilla and cool completely.
- Mix the biscuit crumbs, melted butter, optional sugar, and salt. Press the mixture firmly into the prepared pan and bake for about 10 minutes, then cool slightly.
- Beat the softened cream cheese and sugar on low to medium speed until smooth. Add the eggs and yolk one at a time, mixing just until incorporated, then blend in the sour cream, vanilla, flour or cornstarch, and lemon zest.
- Pour about half of the filling over the crust. Spoon in some cooled rhubarb, add the remaining filling, and dot the surface with the rest of the rhubarb; swirl gently with a skewer or knife.
- Bake for 55–70 minutes, until the edges are set and the center still has a slight wobble. Turn off the oven, leave the cheesecake inside with the door slightly ajar for 30–60 minutes, then cool to room temperature.
- Refrigerate the cheesecake for at least 4 hours, although overnight is best. Remove the pan, warm and wipe a thin knife between cuts, and serve chilled.
Notes
Use full-fat, room-temperature cream cheese and mix gently to avoid lumps and excess air. Cool the rhubarb mixture completely before swirling it into the filling. Store covered in the refrigerator and serve within several days for the freshest texture.
