Combine the graham crumbs, melted butter, sugar, and salt in a bowl. Push the mixture firmly into the bottom of your pan. Pop it in the oven for 10 minutes until it firms up. Take it out and let it sit.

Use your electric mixer to beat the cream cheese, sugar, and flour until it's smooth and creamy (about a minute). Toss in the vanilla, lemon zest, lemon juice, and salt, mixing on low. Add the eggs one by one on low speed. Fold in the sour cream just until it's all mixed together.

Put your springform pan in a big roasting pan. Pour your batter over the crust. Add the boiling water to the roasting pan about an inch deep. Bake for 1 hour 30-45 minutes until it's almost set but still jiggles slightly in the middle. Let it cool in the water bath for 45 minutes, then take off the foil and stick it in the fridge for at least 8 hours.
