Preheat your oven to 400°F (200°C) with a rack in the center. Butter a 10-inch (24 cm) springform pan, then line it with parchment paper, leaving an extra 2 inches (5 cm) inches hanging over the sides.
Using a stand mixer with the paddle attachment, handheld mixer, or wooden spoon, beat the cream cheese and sugar until completely smooth and creamy.
Add the salt, lemon zest and vanilla.
Incorporate the eggs one at a time, beating well after each addition.
Mix in the heavy cream until just combined. Carefully sift the flour evenly over the batter, mixing gently on low until smooth.
Pour the batter into the prepared pan and bake for 50–60 minutes. The cheesecake should rise significantly, develop a deep golden brown (almost burnt) top, and retain a jiggly center.
Remove from the oven and allow it to cool completely on a rack. The cheesecake will sink slightly in the center—this is normal and desirable.
Remove the sides of the springform pan and gently peel away the parchment paper. Serve at room temperature.
