Set the springform pan inside a large roasting pan. Pour the filling over the crust. Carefully pour the boiled water into the roasting pan until it’s about 1 inch deep. Bake for 90–105 minutes until mostly set but just a little jiggly in the center. Let it cool in the water bath for 45 minutes, then take off the foil and chill for at least 8 hours in the fridge.
