I only find cornstarch at local stores. Can I use that instead of corn flour? Or any other flour type to substitute corn flour if I couldn't find it in stores here? Thanks in advance.
The cheesecake is a baked cheesecake and cornflour is added as it helps to stabilise the eggs in the cheesecake batter and also helps the cheesecake to set as it cooks. In the US cornstarch is the same as UK cornflour and should be used for the cheesecake. Also if you slide the "metric-cups" toggle button on the top right hand of the ingredients list to the right you will see the US measurements and ingredients, which may help in the future.
