Part 1: Preparing the Pan and Crust

1. Preheat and Prepare: Position a rack in the middle of your oven and preheat to 350°F (175°C). Take a 9-inch springform pan. To create a waterproof seal for the water bath, wrap the outside of the pan with a double layer of heavy-duty aluminum foil, ensuring it goes all the way up the sides. This is the single most important step to prevent water from seeping into your crust.
2. Make the Crumb Mixture: In a medium bowl, combine the graham cracker crumbs, ¼ cup of granulated sugar, and the pinch of salt. Pour in the melted butter and stir with a fork until all the crumbs are evenly moistened. The texture should resemble wet sand.
3. Press the Crust: Pour the buttery crumbs into your prepared springform pan. Using the flat bottom of a measuring cup or glass, firmly press the crumbs into an even layer across the bottom and about 1 inch up the sides of the pan. A tightly packed crust is essential for clean slices.
4. Pre-Bake the Crust: Place the pan on a baking sheet and bake for 10 minutes. This pre-baking step creates a crispier, more stable base for your filling. Once baked, remove it from the oven and set it aside to cool on a wire rack while you prepare the filling. Reduce the oven temperature to 325°F (165°C).

Part 2: Crafting the Creamy Filling

1. Beat the Cream Cheese: In the large bowl of a stand mixer fitted with the paddle attachment (or using a hand mixer), place the four blocks of room temperature cream cheese. Beat on medium-low speed for 2-3 minutes until it is completely smooth and creamy, with absolutely no lumps. Scrape down the sides and bottom of the bowl frequently. This is the most critical step for a silky, lump-free cheesecake. Do not rush it.
2. Add Sugar and Flour: With the mixer on low, gradually add the 1 ½ cups of granulated sugar and the 3 tablespoons of flour. Mix until just combined, scraping the bowl again to ensure everything is incorporated.
3. Incorporate Wet Ingredients: Add the room temperature sour cream, heavy cream, vanilla extract, and lemon juice. Mix on low speed until the batter is smooth and well-blended. Remember to scrape the bowl one more time. The lemon juice won’t make the cheesecake taste like lemon; it just brightens the flavor and balances the sweetness.
4. Add the Eggs: Add the 4 room temperature eggs and 1 egg yolk, one at a time, mixing on the lowest possible speed after each addition. Mix only until the yellow of the yolk disappears into the batter. Over-mixing at this stage incorporates too much air, which is a primary cause of cheesecake cracking. The final batter should be thick, smooth, and pourable.

Part 3: Assembling, Baking, and Cooling

1. Assemble the Cheesecake: Pour the cream cheese filling over the cooled, pre-baked crust in the springform pan. Use a spatula to spread it into an even layer.
2. Prepare the Water Bath (Bain-Marie): Bring a kettle or pot of water to a boil. Place the foil-wrapped springform pan into a larger roasting pan. Carefully pour the hot water into the roasting pan until it reaches about halfway up the sides of the springform pan. The water bath creates a steamy, humid environment in the oven, which promotes even baking and is the best defense against cracks.
3. Bake the Cheesecake: Carefully transfer the roasting pan to the oven. Bake at 325°F (165°C) for 70-80 minutes. The cheesecake is done when the edges are set and slightly puffed, but the center 2-3 inches still have a slight “jiggle” or “wobble” like Jell-O. Do not over-bake, as this will lead to a dry texture and cracks.
4. The Crucial Cooling Process: This process is as important as the baking itself.

   • Step 1 (Oven Off): Turn the oven off completely. Crack the oven door open with a wooden spoon and let the cheesecake cool slowly in the oven for 1 hour. This gradual temperature change prevents the shock that causes cracking.
   • Step 2 (Room Temp): Carefully remove the cheesecake from the water bath and roasting pan. Remove the foil wrapping. Place the cheesecake on a wire rack and let it cool to room temperature, which will take about 2-3 hours.
   • Step 3 (Refrigerate): Once at room temperature, run a thin knife around the edge of the cheesecake to loosen it from the pan (this also helps prevent cracking as it cools and shrinks). Cover the pan loosely with plastic wrap and refrigerate for at least 6 hours, but preferably overnight. This chilling period is non-negotiable; it allows the cheesecake to fully set and for the flavors to meld and deepen.

Part 4: Topping and Serving

1. Release and Top: Once fully chilled, release the sides of the springform pan. Transfer the cheesecake to a serving platter. Just before serving, spoon the cherry pie filling over the top, spreading it gently and leaving a small border around the edge for a beautiful presentation.
2. Slice and Enjoy: To get clean, perfect slices, use a large, sharp knife. Dip the knife in hot water and wipe it clean between each cut. Serve immediately and accept the compliments!
