Preheat your oven to 350°F (or 177°C) and adjust the rack to lower middle.
Crush graham crackers, mix with sugar and melted butter, press into a springform pan, and pre-bake for ~10 minutes.
Beat cream cheese + sugar until creamy, then add sour cream, lemon juice, and vanilla. Add eggs one by one until just blended.
Prepare a water bath: place the springform pan in a larger roasting pan, pour in the batter, and then pour the boiling water into that roasting pan.
Bake for 55 to 70 minutes, covering with foil if it browns too quickly. Once done, let it sit for about 1 hour with the oven's door cracked open, then remove it from the water bath and cool at room temperature.
Refrigerate it for 4-5 hours or overnight. Before serving, loosen the edges with a sharp knife, remove the pan's rim, and slice. Enjoy your creamy cheesecake!
