Heat the oven to 325°F (165°C). Butter a 10-inch springform pan, line the bottom with parchment, and wrap the outside tightly with two layers of heavy-duty foil.
02 -
Stir graham crumbs, sugar, salt, and melted butter until evenly moistened. Press firmly into the bottom of the pan and bake for 10 minutes, then cool while you make the filling.
03 -
Lower the oven to 300°F (150°C). Beat the cream cheese, softened butter, sugar, and cornstarch on low to medium-low speed until smooth, scraping the bowl well.
04 -
Mix in the sour cream, vanilla, lemon zest, and lemon juice just until the batter is smooth and glossy.
05 -
Add the eggs one at a time on low speed, mixing only until each egg disappears. Scrape the bowl once more and tap it gently on the counter to release large air bubbles.
06 -
Pour the batter over the crust and smooth the top. Set the springform pan in a roasting pan, add hot water halfway up the sides, and bake for 90-105 minutes until the edges are set and the center still has a gentle wobble.

Turn off the oven, crack the door, and let the cheesecake rest inside for 1 hour. Remove from the water bath, cool to room temperature, then cover and refrigerate at least 8 hours or overnight.
