Step 1: Prepare the Pan and Crust
Preheat your oven to 325°F (160°C). Take a 9-inch springform pan and wrap its exterior tightly with two layers of heavy-duty aluminum foil. In a bowl, combine the cracker crumbs, brown sugar, melted butter, and salt. Press firmly onto the bottom of the pan. Bake for 10 minutes, then remove and let cool.
Step 2: The Cream Cheese Alchemy
Using a stand mixer with a paddle attachment on low speed, beat the room-temperature cream cheese alone for 2 minutes until smooth. Gradually add the sugar and beat for another 2 minutes.
Step 3: Infuse with Flavor
Add the vanilla paste (or seeds) and salt. Pour in the room-temperature heavy cream slowly while mixing on the lowest speed.
Step 4: Incorporate Eggs
Add eggs one at a time, mixing gently until each is fully incorporated. Mix in the sour cream until just combined.
Step 5: Water Bath Bake
Place the foil-wrapped pan into a deep roasting pan. Pour the filling over the cooled crust. Carefully pour boiling water into the roasting pan until halfway up the side of the springform. Bake for 55 minutes. The edges should be set, but the center should jiggle slightly.
Step 6: Cool-Down
Turn the oven off, crack the door, and let the cheesecake sit in the oven with the water bath for 1 hour. Remove the pan, run a knife around the edge, and let cool completely on a rack for another 2 hours before refrigerating
