Reduce oven temperature to 148º.

In a large bowl, beat the cream cheese, sugar and flour on low speed until well completely combined and smooth. Be sure to use low speed to reduce the amount of air added to the batter, which can cause cracks. Scrape down the sides of the bowl.

Add the sour cream, lemon juice and lemon zest and mix on low speed until well combined.

Add the eggs one at a time, mixing slowly to combine after each addition, then add the egg yolks and mix until combined. Scrape down the sides of the bowl as needed to make sure everything is combined.

Gently stir the blueberries into the batter.

Pour the cheesecake batter evenly into the crust.

Place the springform pan inside another larger pan. Fill the outside pan with enough warm water to go about halfway up the sides of the pan. The water should not go above the top edge of the aluminium foil on the springform pan.

Bake for 1 hour 15 minutes. The centre should be set, but still jiggly. Turn off the oven and leave the door closed for 30 minutes. The cheesecake will continue to cook, but slowly begin to cool as well.

Crack the door of oven to allow the cheesecake to continue to cool slowly. This process helps prevent cracking.

Remove the cheesecake from the oven and water bath wrapping and place the cheesecake in the refrigeration to cool completely.

Topping

While the cheesecake cools, make the topping. Combine the sugar, corn starch and water in a medium-sized saucepan over medium heat and stir to combine. Heat until the mixture is wet and the sugar begins to melt.

Add the blueberries and stir to coat with the sugar mixture.

Continue to cook until the blueberries start to soften and let out juice.

Remove from the heat when blueberries are a bit juicy and the juice begins to thicken. Pour the mixture in another bowl and refrigerate until cool.

When you are ready to serve the cheesecake, make the whipped cream. Add the heavy whipping cream, powered sugar, and vanilla extract to a large mixer bowl and whip on high speed until stiff peaks form.

Remove the cheesecake from the fridge and remove the sides of the springform pan. Set the cheesecake on a serving plate.

Pipe swirls of whipped cream around the edge of the cheesecake, then top with the blueberry topping and slices of lemon.

Refrigerate cheesecake until ready to serve. Cheesecake is best when stored well covered and best eaten within 3-4 days.
