1-First Step: Prepare the mise en place. Set out cream cheese, eggs, and sour cream to reach room temperature. This prevents lumps and cracks. Grease pan sides lightly. Have foil ready for water bath.

2-Second Step: Make the graham cracker crust. Mix 1 ½ cups graham cracker crumbs, ⅓ cup melted butter, and ¼ cup sugar. Press firmly into pan bottom and 1 inch up sides. Bake 10 minutes at 325°F. Cool 10 minutes. This base supports the heavy filling.

3-Third Step: Mix the filling. Beat 32 oz room-temp cream cheese and 1 cup sugar until smooth, about 2 minutes. Add 3 eggs one at a time, mixing low speed after each. Scrape bowl. Blend in 1 cup sour cream, 1 tsp vanilla, and 2 tbsp flour. Avoid overmixing to keep air minimal.

4-Fourth Step: Assemble and water bath setup. Pour filling over crust. Tap pan to release bubbles. Wrap pan bottom and sides in double foil. Place in larger roasting pan. Add 1 inch hot water to roaster. For vegan adapt: use plant substitutes here.

5-Fifth Step: Bake the cheesecake. Bake at 325°F for 60-70 minutes. Edges set, center 2-3 inches jiggles slightly. Tent foil if browning. Turn off oven, crack door, cool 1 hour inside. This gradual cooling avoids cracks.
