Instructions:
Prepare the Pan: Generously butter the inside of a 10-inch springform pan. Wrap it in a double layer of heavy-duty aluminum foil to prevent water from seeping in during baking.
Preheat Oven: Set your oven to 300°F with the rack in the middle.
Mix Wet Ingredients: In a large mixing bowl, beat the eggs with the sour cream until well combined using an electric mixer.
Cream Cheese and Butter: In a separate bowl, beat the cream cheese with the butter until smooth. Add this to the egg and sour cream mixture, beating until smooth.
Add Flavorings: Mix in the sugar, cornstarch, vanilla extract, lemon juice, and lemon zest. Beat thoroughly for about 2 minutes to ensure everything is well incorporated.
Bake: Pour the batter into the prepared pan. Place the pan inside a roasting pan. Fill the roasting pan with hot tap water halfway up the sides of the springform pan. Bake for 2 hours and 15 minutes, or until a knife inserted into the center comes out clean.
Cool and Chill: Remove the cheesecake from the water bath and carefully peel off the aluminum foil. Let it cool at room temperature for about 4 hours. Refrigerate covered overnight to set completely.
Serving Suggestions
To serve, slice the chilled cheesecake with a sharp knife, dipping it in hot water and wiping it dry between slices for clean cuts. Top with fresh berries, a drizzle of fruit sauce, or enjoy the rich flavor as is.
