Bake your cheesecake in the waterbath for 60 minutes.
Things to look for: Your cheesecake should be firm to the touch on the top, yet slightly wobbly in the middle after baking.
Once you're happy you're at this stage, turn your oven off, leave the door open a little and let your cheesecake cool inside it.
Once it's fully cooled, put the cheesecake in the fridge for a couple of hours to set fully.
