Preheat oven to 165 degrees Celsius, grease 23 cm pan and line bottom with baking paper
In a freezer bag, empty tennis biscuits and crush them using a rolling pin until they are finely crushed
In a separate bowl add the crushed biscuits and Melted butter (the butter must be watery) and combine
Using the back of a 1/4 cup measuring cup, flat layer the buttered biscuit crumbs to the bottom of the pan, and some must be pressed to the sides of the pan
Place the pan into the preheated oven, and set a 10 minutes timer. After 10 minutes of baking, take it out to let it cool
Wrap the pan with heavy foil leaving the top opened. This is to prepare for the baking stage
Drop the stove temperature to 145 degrees Celsius
In a mixing bowl, Mix cream cheese with sugar for about 2 minutes until they are fully combined. Scrape the bowl down and mix again
Add Eggs, one at a time while gently mixing or at low speed if using a mixer
Add Sour cream, vanilla extract, flour into mixing bowl and mix that together for 2 minutes, scrape the bowl down halfway and mix again until well combined
Add the mixture into the Baking pan with cheesecake crust
Take a rectangular pan/ any bigger pan than the 23cm pan, and put the cheesecake pan inside
Add boiling water halfway into the bigger pan, this is called a Hot water bath for the cheesecake to bake in a moist and steamy environment
Place the Pans into the Oven and bake for 1hr 30 minutes
After baking, take out of the water bath, and release the foil while the cheesecake cools
Set the cheesecake in the fridge for 4hour or overnight
Notes
All your ingredients must be at room temperature to avoid having lumps in your cheesecake.
Do not over mix your cheesecake batter, as the final product will be stiff and have cracks .
The best cheesecake is one that bakes in a hot water bath, you don not want to skip this stage.
Add filling of choice on your cheesecake; Berry compote, whipped cream, meringue, fresh fruits, chocolate ganache
Allow your cheesecake to set at least 4 hours in the fridge after cooling or have it the next day.
