Preheat oven to 220°C fan-forced. Line a 23cm springform tin with two overlapping sheets of baking paper, pressed into all crevices, with paper sticking 5cm above the rim. Crumple the paper for texture.
Beat cream cheese and sugar until smooth. Add eggs one at a time, beating after each. Add cream, flour, vanilla, salt. Beat until smooth but not aerated.
Pour into the tin. Tap on counter to release bubbles.
Bake 45-55 minutes. The top should be deeply caramelised, almost black at the edges. The centre should still wobble like jelly when you nudge the tin.
Cool in the tin. Chill at least 3 hours (overnight is better) before slicing. Serve at room temperature for the best texture.
