Prepare the Cheesecake Batter:

1. Beat the Cream Cheese: In a large bowl, beat the softened cream cheese and sugar until smooth and creamy. Add the sour cream and vanilla extract, mixing until fully combined.
2. Add the Mango Puree: Stir in the mango puree until smooth.
3. Add the Dry Ingredients: Sift the flour and cornstarch together and fold them into the mango mixture.
4. Separate and Whisk the Eggs: Separate the eggs, placing the yolks in one bowl and the whites in another. Beat the egg yolks into the cream cheese mixture one at a time until fully incorporated.
5. Whisk the Egg Whites: In a clean, dry bowl, beat the egg whites with cream of tartar until soft peaks form. Gradually add sugar and continue beating until stiff peaks form.
6. Fold the Egg Whites: Gently fold the whipped egg whites into the mango mixture, a little at a time, being careful not to deflate the batter. Fold until just combined.

Bake the Cheesecake:

1. Prepare a Water Bath: Place the springform pan in a larger pan and pour hot water into the larger pan until it reaches halfway up the sides of the springform pan. This helps the cheesecake cook evenly and prevents cracking.
2. Bake: Preheat the oven to 320°F (160°C). Bake the cheesecake for 50-60 minutes, or until the top is lightly golden and a toothpick inserted into the center comes out mostly clean. The cheesecake will rise during baking, then settle once it cools.
3. Cool the Cheesecake: Once baked, turn off the oven and leave the cheesecake inside with the door slightly ajar for 1 hour to cool gradually. This helps prevent cracking.
4. Chill: After the cheesecake has cooled to room temperature, refrigerate it for at least 4 hours, or overnight for the best flavor and texture.

Finish and Serve:

1. Top with Mango Glaze: Once the cheesecake has chilled, carefully spread the cooled mango glaze over the top for a smooth, glossy finish.
2. Slice and Serve: Gently release the cheesecake from the springform pan, slice, and serve chilled. Garnish with fresh mango slices or mint leaves for an extra tropical touch.
